DESCRIPTION
The uA9638C is a dual high-speed differential line driver designed to meet ANSI Standard EIA/TIA-422-B. The
inputs are TTL and CMOS compatible and have input clamp diodes. Schottky-diode-clamped transistors are
used to minimize propagation delay time. This device operates from a single 5-V power supply and is supplied in
an 8-pin package.
The uA9638 provides the current needed to drive low-impedance loads at high speeds. Typically used with
twisted-pair cabling and differential receiver(s), base-band data transmission can be accomplished up to and
exceeding 15 Mbps in properly designed systems. The uA9637A dual line receiver is commonly used as the
receiver. For even faster switching speeds in the same pin configuration, see the SN75ALS191.
The uA9638C is characterized for operation from -40°C to 85°C.
