Operating from a single V power supply, a highly efficient on-chip charge pump using small (0. µf) external capacitors allows bipolar levels to be developed. Two drivers and two receivers are provided on each device. The devices are fabricated on BiCMOS, an advanced mixed technology process that combines low power CMOS with highspeed bipolar circuitry. This allows for transmission rates up to 200 kb/s, yet minimizes the quiescent power supply current to under ma. The ADM232A is a pin-compatible, high-speed upgrade for the AD232 and for the ADM232L. It is available in 6-lead DIP and in both narrow and wide surface-mount (SOIC) packages. The ADM222 contains an additional shutdown (SHDN) function that may be used to disable the device, thereby reducing the supply current to 0. µa. During shutdown, all transmit/receive High-Speed, V, 0.

The ADM222 is available in -lead DIP and in a wide surface-mount (SOIC) package. The ADM242 combines both shutdown (SHDN) and enable (EN) functions. The shutdown function reduces the supply current to 0. ma. During shutdown, the transmitters are disabled but the receivers continue to operate normally. The enable function allows the receiver outputs to be disabled thereby facilitating sharing a common bus. The ADM242 is available in -lead DIP and in a wide surface-mount (SOIC) package.

7 GENERAL INFORMATION The ADM222/ADM232A/ADM242 are high-speed drivers/receivers requiring a single digital V supply. The standard requires transmitters that will deliver ± V minimum on the transmission channel and receivers that can accept signal levels down to ± 3 V. The parts achieve this by integrating stepup voltage converters and level-shifting transmitters and receivers onto the same chip. CMOS technology is used to keep the power dissipation to an absolute minimum. All devices contain an internal charge pump voltage doubler and a voltage inverter that generates ± 0 V from the V input. Four external 0. µf capacitors are required for the internal charge pump voltage converter. The ADM222/ADM232A/ADM242 is a modification, enhancement and improvement to the AD230-AD24 family and derivatives thereof. It is essentially plug-in-compatible and does not have materially different applications. CIRCUIT DESCRIPTION The internal circuitry consists of four main sections. These are: Charge Pump Voltage Converter to Transmitters to Receivers Enable and Shutdown Functions. Charge Pump DC-DC Voltage Converter The Charge Pump Voltage converter consists of an oscillator and a switching matrix. The converter generates a ±0 V supply from the input V level. This is done in two stages using a switched capacitor technique. The V input supply is doubled to 0 V using capacitor C as the charge storage element. The 0 V level is also generated from the input V supply using C and C2 as the storage elements. Capacitors C3 and C4 are used to reduce the output ripple. Their values are not critical and can be reduced if higher levels of ripple are acceptable. The charge pump capacitors C and C2 may also be reduced at the expense of higher output impedance on the and supplies. The and supplies may also be used to power external circuitry if the current requirements are small. Please refer to the typical performance characteristics which shows the, output voltage vs. current. In the shutdown mode the charge pump is disabled and decays to while decays to 0 V. Transmitter (Driver) Section The Drivers convert input levels into output levels. With = V and driving a typical load, the output voltage swing is ± V. Even under worst-case conditions the drivers are guaranteed to meet the ± V minimum requirement. The input threshold levels are both TTL- and CMOS-compatible with the switching threshold set at /4. With a nominal = V, the switching threshold is.2 V typical. Unused inputs may be left unconnected, as an internal 400 kω pull-up resistor pulls them high forcing the outputs into a low state. As required by the standard, the slew rate is limited to less than 30 V/µs without the need for an external slew limiting capacitor, and the output impedance in the power-off state is greater than 300 Ω. Receiver Section The receivers are inverting level-shifters that accept input levels (±3 V to ± V) and translate them into V TTL/ CMOS levels. The inputs have internal kω pull-down resistors to ground and are also protected against overvoltages of up to ± 30 V. The guaranteed switching thresholds are 0. V minimum and 2.4 V maximum, which are well within the ± 3 V requirement. The low level threshold is deliberately positive as it ensures that an unconnected input will be interpreted as a low level. The receivers have Schmitt trigger input with a hysteresis level of 0. V. This ensures error-free reception for both noisy inputs and for inputs with slow transition times Enable and Shutdown Functions On the ADM222, both receivers are fully disabled during shutdown. On the ADM242, both receivers continue to operate normally. This function is useful for monitoring activity so that when it occurs, the device can be taken out of the shutdown mode. The ADM242 also contains a receiver enable function (EN) which can be used to fully disable the receivers, independent of SHDN.
