SN75ALS174DWR Description

Short technical summary and product information.

The SN75ALS174DWR from Texas Instruments is a quad differential line driver featuring a tri-state differential output. It is designed to meet or exceed ANSI standard EIA/TIA-422-B and RS-485 requirements, making it suitable for multipoint balanced bus transmission.

 

This device is optimized for operation at speeds up to 20 Mbps, supporting both serial and parallel applications. Each driver offers a wide positive and negative common-mode output voltage range, which is beneficial for party-line applications in noisy environments. The SN75ALS174DWR includes positive and negative current limiting and thermal shutdown protection to safeguard against line fault conditions on the transmission bus lines.

 

With an operating temperature range of 0°C to 70°C, this line driver is suitable for various industrial applications. It is available in a 20-SOIC package and features surface mount technology for easy integration into circuit designs. The device has 4 transmitters and 0 receivers, operating in half-duplex mode.

 

Key electrical characteristics include a maximum signaling rate of 20 Mbps, fault protection from -10V to 15V, and a common-mode range of -7V to 12V. The supply current is a maximum of 55mA, and it supports up to 32 nodes on the bus.
