Overview
The AD7306JR, produced by Analog Devices Inc., is a 5 V monolithic line driver/receiver designed to provide an interface between TTL signal levels and dual standard EIA RS-232/RS-422 signal levels. This component is particularly useful in applications where compatibility with both RS-232 and RS-422 standards is necessary. It operates from a single +5 V power supply, facilitated by an internal charge pump voltage converter that generates ±10 V levels, eliminating the need for external bipolar power supplies.
