ADM202 - Analog Devices

ADM202 CMOS RS-232 Driver/Receiver

The ADM202 is a 2-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. This converter generates ±10 V RS-232 output levels. The ADM202 meets or exceeds the TIA/EIA-232-E and V.28 specific.
