The SN65HVD12DR from Texas Instruments is a half-duplex differential transceiver supporting RS-485 and RS-422 protocols. It operates with a single 3.3V supply and is designed for balanced transmission lines, meeting ANSI TIA/EIA-485-A standards.
Key electrical features include a data rate of 1Mbps, receiver hysteresis of 35mV, and bus-pin ESD protection exceeding 16kV HBM. It also offers a low-current standby mode with a typical current draw of 1µA. Optional driver output transition times are available for signaling rates of 1Mbps, 10Mbps, and 32Mbps.
This transceiver is suitable for applications requiring robust communication over balanced lines. It features fail-safe receivers for open-circuit, idle-bus, and shorted-bus conditions, along with thermal shutdown protection and glitch-free power-up/down for hot-plugging.
The SN65HVD12DR is supplied in an 8-pin SOIC package suitable for surface mounting. It operates within a temperature range of -40°C to 85°C.
