Overview
The SN65HVD12IDREP is a 3.3-V RS-485 transceiver produced by Texas Instruments. This component combines a 3-state differential line driver and a differential input line receiver, designed to operate with a single 3.3 V power supply. It meets or exceeds the requirements of ANSI standard TIA/EIA-485-A and ISO 8482:1993, making it suitable for bidirectional data communication on multipoint bus-transmission lines. The device is particularly useful in applications requiring reliable and robust communication over balanced transmission lines.
