19-1452; Rev 1; 1/99 Quad, Rail-to-Rail, Fault-Protected, General Description The quad, single-pole/double-throw (SPDT), fault-protected analog switch is pin-compatible with the industry-standard MAX333 and MAX333A. The features fault-protected inputs and Rail-to-Rail signal handling. The normally open (NO_ ) and normally closed ( ) terminals are protected from overvoltage faults up to ±25V with power on and up to ±4V with power off. During a fault condition, NO_ and become high impedance with only nanoamperes of leakage current flowing to the source. In addition, the output () clamps to the appropriate polarity supply rail and provides up to ±1mA of load current. This ensures unambiguous rail-to-rail outputs when a fault occurs. The operates from dual ±4.5V to ±18V power supplies or a single +9V to +36V supply. All digital inputs have +.8V and +2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±15V supplies or a +12V supply. On-resistance is 175Ω max and is matched between switches to 1Ω max. The offleakage current is only.5 at TA = and 1 at TA = +85 C.

Detailed Description The is a fault-protected analog switch with special operation and construction. Traditional fault-protected switches are constructed using three-series CMOS devices. This combination produces good fault protection but fairly high on-resistance when the signals are within about 3V of each supply rail. These series devices are not capable of handling signals up to the power-supply rails. The differs considerably from traditional faultprotected switches, with three advantages. First, it is constructed with two parallel FETs, allowing very low on-resistance when the switch is on. Second, they allow signals on the or NO_ pins that are within or slightly beyond the supply rails to be passed through the switch to the terminal, allowing rail-to-rail signal operation. Third, when a signal on or NO_ exceeds the supply rails by about 15mV (a fault condition), the voltage on is limited to the appropriate polarity supply voltage. Operation is identical for both fault polarities. The fault-protection extends to ±25V with power on and ±4V with power off. The has a parallel N-channel and P-channel MOSFET switch configuration with input voltage sensors. The simplified internal structure is shown in Figure 1. The parallel N1 and P1 MOSFETs form the switch element. N3 and P3 are sensor elements to sample the input voltage and compare it against the power-supply rails. 8

When the input voltage is raised above either supply rail, the internal sense and comparator circuitries (N3 and N-channel driver or P3 and P-channel driver) disconnect the output () from the input (Figure 1). If the switch driven above the supply rail has an on state, the clamp circuitries (N2 or P2) connect the output to the appropriate supply rail. Table 1 summarizes the s operation under normal and fault conditions. Row 5 shows a negative fault condition when the supplies are on. It shows that with supplies of ±15V, if the input voltage is between -15V and -25V, the output () clamps to the negative supply rail of -15V. With this technique, the SPDT switch is capable of withstanding a worse-case condition of opposite fault polarities at its inputs. +15V COMPARATOR Figure 1. Simplified Internal Structure During normal operation of a conducting channel, N1 and P1 remain on with a typical 125Ω on-resistance between NO_ (or ) and. If the input voltage exceeds either supply rail by about 15mV, the parallel combination switches (N1, P1) are forced off through the driver and sensing circuitries. At the same time, the output ( ) is clamped to the appropriate supply rail by the clamp circuitries (N2, P2). Two clamp circuits limit the output voltage to the supply voltages. For simplicity, Figure 1 shows only one side of the SPDT switch configuration. The complete circuit is composed of two channels with their outputs connected. Normal Operation Two comparators continuously compare the voltage on the NO_ (or ) pin with and supply voltages. When the signal on NO_ (or ) is between and, the switch behaves normally, with FETs N1 and P1 turning on and off in response to NO_ (or ) signals (Figure 1). For any voltage between the supply rails, the switch is bidirectional; therefore, and (or NO_ ) are interchangeable. Only NO_ and can be exposed to overvoltages beyond the supply range and within the specified breakdown limits of the device. Transient Fault Condition When a fast rising or falling transient on NO_ (or ) exceeds or, the output () follows the input (IN_) to the supply rail by only a few nanoseconds. This delay is due to the switch on-resistance and circuit capacitance to ground. However, when the input transient returns to within the supply rails there is a longer recovery time. For positive faults, the recovery time is typically 2.5µs. For negative faults, the recovery time is typically 1.3µs. These values depend on the output resistance and capacitance. The delays are not dependent on the fault amplitude. Higher output resistance and capacitance increase the recovery times. Fault Protection, Voltage, and Power Off The maximum fault voltage on the NO_ or pins is ±4V from ground when the power is off. With ±15V supply voltages, the highest voltage on NO_ (or ) can be +25V, and the lowest voltage on NO_ (or ) can be -25V. Exceeding these limits can damage the chip. IN_ Logic-Level Thresholds The logic-level thresholds are TTL/CMOS-compatible when is +15V. Raising increases the threshold slightly; when reaches +25V, the level threshold is 2.8V higher than the TTL output high-level minimum of 2.4V, but still compatible with CMOS outputs (see the Typical Operating Characteristics). Increasing has no effect on the logic-level thresholds, but it does increase the gate-drive voltage to the signal FETs, reducing their on-resistance. 9

NO_ OUTPUT Failure Modes The is not a lightning arrester or surge protector. Exceeding the fault-protection voltage limits on NO_ or, even for very short periods, can cause the device to fail. Applications Information Ground There is no connection between the analog signal paths and GND. The analog signal paths consist of an N-channel and P-channel MOSFET with their sources and drains paralleled and their gates driven out of phase to and by the logic-level translators. and GND power the internal logic and logic-level translators and set the input logic thresholds. The logiclevel translators convert the logic levels to switched and signals to drive the gates of the switches. This drive signal is the only connection between the power supplies and the analog signals. GND, IN_, and have ESD protection diodes to and. Supply Current Reduction When the logic signals are driven rail-to-rail from to +12V or -15V to +15V, the supply current reduces to approximately half of the supply current when the logic input levels are at to 5V. Power Supplies The operates with bipolar supplies between ±4.5V and ±18V. The and supplies need not be symmetrical, but their difference can not exceed the absolute maximum rating of +44V. The operates from a single supply between +9V and +36V when is connected to GND.
