Overview
The SN65HVD12DR is a 3.3-V differential bus transceiver produced by Texas Instruments. It combines a 3-state differential line driver and a differential input line receiver, designed for bidirectional data communication on multipoint bus-transmission lines. This device operates with a single 3.3-V power supply and meets or exceeds the requirements of ANSI standard TIA/EIA-485-A and ISO 8482:1993. The SN65HVD12DR is encapsulated in an 8-pin SOIC package and is suitable for a wide range of applications requiring reliable and efficient data transmission.
