SN65LBC179QDRG4 Description

Short technical summary and product information.

The SN65LBC179QDRG4 is a transceiver IC from Texas Instruments designed for differential data transmission. It operates with a supply voltage range of 4.75V to 5.25V and supports both RS422 and RS485 protocols.

 

This device features one transmitter and one receiver, operating in full duplex mode. It has a maximum signaling rate of 10 Mbps and a common-mode voltage range of -7V to 12V. The transceiver includes fault protection from -10V to 15V and supports up to 32 nodes on the bus. Its operating temperature range is -40°C to 125°C.

 

The SN65LBC179QDRG4 is available in an 8-SOIC package and is designed for surface mounting. It meets or exceeds ANSI RS-485 and ISO 8482:1987(E) standards, making it suitable for high-speed multipoint data transmission over long cables. The low supply current of 5mA or less and features like thermal shutdown protection enhance its usability in various applications.
