SN75HVD12D Description

Short technical summary and product information.

The Texas Instruments SN75HVD12D is a half-duplex differential transceiver operating with a single 3.3-V power supply. It combines a 3-state differential line driver and a differential input line receiver, making it suitable for balanced communication protocols like RS-485 and RS-422.

 

This transceiver supports a maximum signaling rate of 1 Mbps and offers a wide common-mode voltage range of -7 V to 12 V. It includes features such as bus-pin ESD protection exceeding 16-kV HBM, bus-pin short-circuit protection from -7 V to 12 V, and open-circuit, idle-bus, and shorted-bus fail-safe receiver functionality. Thermal shutdown protection and glitch-free power-up/down protection for hot-plugging applications are also integrated.

 

The SN75HVD12D is available in an 8-SOIC package and is designed for surface mounting. It meets or exceeds the requirements of the ANSI TIA/EIA-485-A standard, making it a reliable choice for robust serial communication systems. The device also features a low-current standby mode, consuming only 1 µA typical.
