Overview
The ADM232AARN is a high-speed RS-232 line driver/receiver produced by Analog Devices Inc. This component is part of the ADM222, ADM232A, and ADM242 family, which offers transmission rates up to 200 kB/s. It operates from a single 5 V power supply and utilizes an advanced BiCMOS process, combining low power CMOS with high-speed bipolar circuitry. This design ensures high transmission rates while minimizing power consumption.
