Overview
The UA9638CPG4, produced by Texas Instruments, is a dual high-speed differential line driver designed to meet the ANSI Standard EIA/TIA-422-B. This device is optimized for high-speed data transmission and is particularly useful in applications requiring reliable and fast differential signaling.
The UA9638CPG4 operates from a single 5V power supply and is available in 8-pin packages, including SOIC and PDIP. It features TTL and CMOS compatible inputs with input clamp diodes and uses Schottky-diode-clamped transistors to minimize propagation delay time. This makes it suitable for driving low-impedance loads at high speeds, typically up to 15 Mbps, when used with twisted-pair cabling and differential receivers like the UA9637A.
