SN65LBC184DR RS-485 transceiver IC differential bus driver Chip Detailed Overview
The SN65LBC184DR from Texas Instruments is a robust, high-speed differential bus transceiver designed for RS-485 and RS-422 communication networks. It features ±60V fault protection on bus pins, making it highly resistant to electrical transients, surges, and ESD events, which is critical for industrial and automotive applications. The device supports data rates up to 250kbps, ensuring reliable long-distance communication in noisy environments.
Housed in an 8-pin SOIC package, the SN65LBC184DR integrates a single differential driver and receiver, operating from a 4.75V to 5.25V supply voltage. It includes thermal shutdown protection and current-limiting circuitry, preventing damage from short circuits or excessive power dissipation. The low-power shutdown mode reduces current consumption when the device is inactive, enhancing energy efficiency in battery-powered systems.
The SN65LBC184DR is widely used in factory automation, motor control, and building automation systems, where robust serial communication is essential. Its high input impedance allows up to 32 unit loads on a single bus, supporting multi-node networks. The device operates over an industrial temperature range (-40°C to +85°C), ensuring reliability in harsh conditions.
Alternative 1/1 Transceiver Models & Key Features:
