Overview
The SN65HVD11DRG4 is a 3.3-V differential transceiver produced by Texas Instruments. It is designed for bidirectional data communication on multipoint bus-transmission lines and is part of the SN65HVD11 series. This monolithic integrated circuit combines a 3-state differential line driver and a differential input line receiver, operating with a single 3.3-V power supply. It meets or exceeds the requirements of ANSI TIA/EIA-485-A and ISO 8482:1993 standards, making it suitable for various industrial and commercial applications.
