SN55110AJ

SN55110AJ Description

The SN55110AJ from Texas Instruments is a high-performance dual-line driver designed for robust signal transmission in demanding industrial and communication systems. Housed in a 14-CDIP (Ceramic Dual In-Line Package), this through-hole-mounted IC operates over a ±4.5V to 5.5V supply range, ensuring compatibility with standard TTL and CMOS logic levels. As a 2/0 (two drivers, zero receivers) configuration, it excels in unidirectional data transmission, making it ideal for applications requiring high noise immunity and reliable signal integrity. The device is RoHS3 compliant and features a tube packaging for secure handling and storage.

SN55110AJ Features

• Dual-Line Driver: Supports two independent driver channels for flexible system design.
• Wide Voltage Range: Operates at ±4.5V to 5.5V, accommodating diverse power supply conditions.
