The SN65HVD34DR from Texas Instruments is a 3.3V full-duplex transceiver designed for RS-422 and RS-485 data transmission. It integrates one driver and one receiver, each with separate input and output pins for flexible full-duplex communication.
This transceiver supports signaling rates up to 5Mbps and operates over a wide temperature range of -40°C to 85°C. Key electrical features include a common-mode voltage range of -7V to 12V and fault protection from -9V to 14V. It is designed to support up to 256 nodes on the bus, with bus-pin ESD protection exceeding 15kV HBM.
Packaged in a 14-SOIC surface-mount form factor, the SN65HVD34DR offers features like low-current standby mode (<1µA), glitch-free power-up/down for hot-plugging, 5V tolerant inputs, and failsafe protection for bus idle, open, and short-circuit conditions. Driver current limiting and thermal shutdown are also included for enhanced reliability.
This component is ideal for applications requiring reliable serial communication over long cable lengths, such as industrial automation, building control systems, and point-of-sale (POS) terminals.
