Overview
The ADM232AARWZ-REEL 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. Fabricated on BiCMOS, an advanced mixed technology process combining low power CMOS with high-speed bipolar circuitry, it enables efficient and high-speed data transmission. The device operates from a single 5 V power supply and uses a highly efficient on-chip charge pump with small external capacitors to generate RS-232 bipolar levels.
