SN65HVD12D Description

Short technical summary and product information.

The SN65HVD12D from Texas Instruments is a 3.3V differential transceiver designed for RS-485 and RS-422 communication. This half-duplex device integrates a 3-state differential line driver and a differential input line receiver, operating from a single 3.3V power supply.

Key electrical specifications include a maximum signaling rate of 1 Mbps, with optional transition times supporting up to 32 Mbps. It offers a wide fault protection range of -9V to 14V and a common-mode voltage range of -7V to 12V. The transceiver supports up to 256 nodes on the bus, making it suitable for multi-drop networks.

Designed for robust operation, the SN65HVD12D features bus-pin ESD protection exceeding 16-kV HBM, bus-pin short-circuit protection from -7V to 12V, and thermal shutdown protection. It also includes glitch-free power-up and power-down protection for hot-plugging applications and open-circuit, idle-bus, and shorted-bus fail-safe receiver functionality.

Available in SOIC and PDIP packages, the SN65HVD12D operates within a temperature range of -40°C to 85°C. Its low-current standby mode consumes only 1 µA typical, contributing to power efficiency in embedded systems.
