5962-8515509RA

Overview

The Texas Instruments 5962-8515509RA is a military-grade quadruple differential line driver designed for RS-422 communication interfaces. It operates within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum quiescent current of 25 mA. The device supports data transmission rates up to 10 Mbps and functions reliably across an extended temperature range from -55°C to +125°C. Packaged in a CPAK-16 ceramic flat package, this component provides four independent drivers with high output voltage swing capabilities suitable for demanding industrial and aerospace applications.
