DATASHEET Low-Voltage, Single and Dual Supply, 8-to-1 Multiplexer The Intersil device contains precision, bidirectional, analog switches configured as an 8-to-1 multiplexer/demultiplexer. It was designed to operate from a single +2V to +12V single supply or from dual ±2V to ±6V supplies. The device has an inhibit pin to simultaneously open all signal paths. The has an ON-resistance of 39 with a dual ±5V supply and 125 with a single +3.3V supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only.2na at +25 or.2na at +85. All digital inputs have.8v to 2.4V logic thresholds, ensuring TTL/MOS logic compatibility when using a single 3.3V or +5V supply or dual ±5V supplies. The is a single 8-to-1 multiplexer device.

Detailed Description The multiplexer offers precise switching capability from bipolar ±2V to ±6V supplies or a single 2V to 12V supply. When powered with dual ±5V supplies the part has low ON-resistance (39 ) and high speed operation (t ON = 38ns, t OFF = 19ns). It has an inhibit pin to simultaneously open all signal paths. The device is especially well suited for applications using ±5V supplies. With ±5V supplies the performance (r ON, Leakage, harge Injection, etc.) is best in class. High frequency applications also benefit from the wide bandwidth and high off-isolation. Supply Sequencing And Overvoltage Protection With any MOS device, proper power supply sequencing is required to protect the device from excessive input currents which might permanently damage the I. All I/O pins contain ESD protection diodes from the pin to and to (see Figure 7). To prevent forward biasing these diodes, and must be applied before any input signals, and input signal voltages must remain between and. If these conditions cannot be guaranteed, then one of the following two protection methods should be employed. Logic inputs can easily be protected by adding a 1k resistor in series with the input (see Figure 7). The resistor limits the input current below the threshold that produces permanent damage, and the sub-microamp input current produces an insignificant voltage drop during normal operation. This method is not applicable for the signal path inputs. Adding a series resistor to the switch input defeats the purpose of using a low r ON switch, so two small signal diodes can be added in series with the supply pins to provide overvoltage protection for all pins (see Figure 7). These additional diodes limit the analog signal from 1V below to 1V above. The low leakage current performance is unaffected by this approach, but the switch resistance may increase, especially at low supply voltages. OPTIONAL PROTETION RESISTOR FOR S 1k V NOx OPTIONAL PROTETION DIODE V Power-Supply onsiderations The construction is typical of most MOS analog switches, in that it has three supply pins:,, and GND. and drive the internal MOS switches and set their analog voltage limits, so there are no connections between the analog signal path and GND. Unlike switches with a 13V maximum supply voltage, the 15V maximum supply voltage provides plenty of room for the 1% tolerance of 12V supplies (±6V or 12V single supply), as well as room for overshoot and noise spikes. The part performs equally well when operated with bipolar or single voltage supplies.the minimum recommended supply voltage is 2V single supply or ±2V dual supply. It is important to note that the input signal range, switching times, and ON-resistance degrade at lower supply voltages. Refer to the Electrical Specification tables on page 4 and Typical Performance urves on page 11 for details. and GND power the internal logic setting the digital switching point of the level shifters. The level shifters convert the logic levels to switched and signals to drive the analog switch gate terminals. Logic-Level Thresholds and GND power the internal logic stages, so has no affect on logic thresholds. This is TTL compatible (.8V and 2.4V) over a supply range of 2.7V to 1V. At 12V the V IH level is about 3.3V. This is still below the MOS guaranteed high output minimum level of 4V, but noise margin is reduced. For best results with a 12V supply, use a logic family that provides a V OH greater than 4V. The digital input stages draw supply current whenever the digital input voltage is not at one of the supply rails. Driving the digital input signals from GND to with a fast transition time minimizes power dissipation. High-Frequency Performance In systems, signal response is reasonably flat even past MHz (see Figures 16 and 17). Figures 16 and 17 also illustrate that the frequency response is very consistent over varying analog signal levels. An OFF switch acts like a capacitor and passes higher frequencies with less attenuation, resulting in signal feed through from a switch s input to its output. Off-isolation is the resistance to this feed through. Figure 18 details the high off isolation of the. At 1MHz, off-isolation is about 55dB in systems, decreasing approximately 2dB per decade as frequency increases. Higher load impedances decrease off-isolation due to the voltage divider action of the switch OFF impedance and the load impedance. OPTIONAL PROTETION DIODE FIGURE 7.

Leakage onsiderations Reverse ESD protection diodes are internally connected between each analog-signal pin and both and. One of these diodes conducts if any analog signal exceeds or. Virtually all the analog leakage current comes from the ESD diodes to or. Although the ESD diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. Each is biased by either or and the analog signal. This means their leakages will vary as the signal varies. The difference in the two diode leakages to the and pins constitutes the analog-signal-path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage currents of the same or opposite polarity. There is no connection between the analog signal paths and GND.
