This allows for transmission rates up to 200 kB/s, yet minimizes the quiescent power supply current to under 5 mA. The ADM232A is a pin-compatible, high-speed upgrade for the AD232 and for the ADM232L. It is available in 16-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 0.1 µA. During shutdown, all transmit/receive REV. C EN GND The ADM222, ADM232A, ADM242 are a family of high-speed RS-232 line drivers/receivers offering transmission rates up to 200 kB/s. Operating from a single 5 V power supply, a highly efficient on-chip charge pump using small (0.1 µF) external capacitors allows RS-232 bipolar levels to be developed. Two RS-232 drivers and two RS-232 receivers are provided on each device. 0.1

The ADM222 is available in 18-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 0.1 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 18-lead DIP and in a wide surface-mount (SOIC) package.

C ADM222/ADM232A/ADM242 GENERAL INFORMATION The ADM222/ADM232A/ADM242 are high-speed RS-232 drivers/receivers requiring a single digital 5 V supply. The RS-232 standard requires transmitters that will deliver ± 5 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 ± 10 V from the 5 V input. Four external 0.1 µF capacitors are required for the internal charge pump voltage converter. The ADM222/ADM232A/ADM242 is a modification, enhancement and improvement to the AD230-AD241 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 TTL/CMOS to RS-232 Transmitters RS-232 to TTL/CMOS 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 ± 10 V supply from the input 5 V level. This is done in two stages using a switched capacitor technique. The 5 V input supply is doubled to 10 V using capacitor C1 as the charge storage element. The –10 V level is also generated from the input 5 V supply using C1 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 C1 and C2 may also be reduced at the expense of higher output impedance on the V+ and V– supplies. The input threshold levels are both TTL- and CMOS-compatible with the switching threshold set at VCC/4. With a nominal VCC = 5 V, the switching threshold is 1.25 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 RS-232 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 RS-232 input levels (± 3 V to ± 15 V) and translate them into 5 V TTL/ CMOS levels. The inputs have internal 5 kΩ pull-down resistors to ground and are also protected against overvoltages of up to ± 30 V. The guaranteed switching thresholds are 0.8 V minimum and 2.4 V maximum, which are well within the ± 3 V RS-232 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 0.5 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. APPLICATIONS INFORMATION A selection of typical operating circuits is shown in TPCs 1–6 and Figure 13. The V+ and V– 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 V+, V– output voltage vs. current. A1 2.0V 5V 5V 100 90 In the shutdown mode the charge pump is disabled and V+ decays to VCC while V– decays to 0 V. 10 Transmitter (Driver) Section 0% The Drivers convert TTL/CMOS input levels into RS-232 output levels. With VCC = 5 V and driving a typical RS-232 load, the output voltage swing is ± 9 V. Even under worst-case conditions the drivers are guaranteed to meet the ± 5 V RS-232 minimum requirement. REV. C 5
