Introduction

AI Translation

A high-performance RS-485 half-duplex transceiver designed for demanding industrial and home-appliance environments. The bus pins withstand high-level ESD events, protecting the internal circuitry from damage.

The bus port features a fault protection voltage of ±65V and an extended common-mode voltage range of ±40V (at a supply voltage of 4.5V to 5.5V), supporting long-cable communication applications. The device integrates one driver and one receiver, operating over a supply voltage range of 3V to 5.5V.

The driver employs slew-rate limiting to reduce EMI, supporting data rates up to 500kbps. The receiver incorporates a fail-safe circuit to ensure the receiver output remains high when the bus inputs are open, shorted, or idle. The bus input ports feature 1/8 unit load impedance, allowing up to 256 transceivers on a single bus.

The device is available in a standard narrow-body SOIC8 package, with an operating temperature range of –40°C to 125°C under natural convection conditions.
