The ADM202/ADM203 is a two-channel RS-232 line driver/ receiver pair designed to operate from a single +5 V power supply. A highly efficient on-chip charge pump design permits RS-232 levels to be developed using charge pump capacitors as small as 0.1 µF. The capacitors are internal to the package on the ADM203 so no external capacitors are required. These converters generate ±10 V RS-232 output levels.

The ADM202/ADM203 meets or exceeds the EIA-232-E and V.28 specifications. Fast driver slew rates permit operation up to 120 kB while high drive currents allows for extended cable lengths.

An epitaxial BiCMOS construction minimizes power consumption to 10 mW and also guards against latch-up. Overvoltage protection is provided allowing the receiver inputs to withstand continuous voltages in excess of ±30 V. In addition, all pins contain ESD protection to levels greater than 2 kV.

The ADM202 is available in 16-lead DIP and both narrow and wide SOIC packages. The ADM203 is available in a 20-pin DIP package.
