SN75LBC174DW Description

Short technical summary and product information.

The SN75LBC174DW from Texas Instruments is a monolithic, quadruple, differential line driver with 3-state outputs, designed to meet EIA-485 standards. It is optimized for high-speed multipoint bus transmission, supporting data rates up to and exceeding 10 million bits per second (10 Mbps).

 

This driver features a wide common-mode output voltage range of -7V to 12V and includes positive- and negative-current limiting, as well as thermal shutdown protection, making it suitable for noisy environments and party-line applications. The device operates over a temperature range of 0°C to 70°C and requires a supply voltage of 4.75V to 5.25V.

 

The SN75LBC174DW is available in a 20-SOIC package and is designed for surface mount applications. Its low power consumption of 1.5mA maximum when the output is disabled contributes to its efficiency. This component is functionally interchangeable with the SN75174.
