SN65HVD33MDREP

The SN65HVD33MDREP from Texas Instruments is a 3.3V full-duplex RS-485 transceiver, suitable for RS-422 and RS-485 data transmission over cable lengths up to 1500 meters. This device integrates one differential line driver and one differential-input line receiver, each with separate input and output pins for flexible full-duplex communication designs.

Key electrical specifications include a signaling rate of up to 26 Mbps, a wide common-mode range of -7V to 12V, and fault protection from -9V to 14V. It operates within a voltage range of 3V to 3.6V and supports up to 64 nodes on the bus, with an optional unit-load option for up to 256 nodes. The transceiver also features 5-V tolerant inputs, bus idle/open/short-circuit failsafe protection, driver current limiting, and thermal shutdown.

Designed for demanding environments, the SN65HVD33MDREP operates from -55°C to 125°C. It includes glitch-free power-up and power-down protection for hot-plugging applications and a low-current standby mode consuming less than 1 µA. The component offers enhanced bus-pin ESD protection exceeding 15-kV HBM.

This transceiver is available in a 14-SOIC package with surface mount mounting type. It is designed for applications requiring reliable serial communication in industrial and automotive environments.
