Overview
The AD7306JRZ is a 5 V monolithic line driver/receiver produced by Analog Devices Inc. This component provides an interface between TTL signal levels and dual standard EIA RS-232/RS-422 signal levels. It is designed to operate from a single +5 V power supply and includes an internal charge pump voltage converter to generate the necessary ±10 V levels for RS-232 output without external bipolar power supplies. The device contains two RS-232 drivers, one RS-422 driver, one RS-232 receiver, and one receiver path that can be configured as either RS-232 or RS-422.
