UA9638
- Meets or exceeds ANSI standard EIA/TIA-422-B
- Operates from a single 5V power supply
- Drives loads as low as 50Ω up to 15Mbps
- TTL- and CMOS-input compatibility
- Output short-circuit protection
- Interchangeable with DS9638
The uA9638 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 5V 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 15Mbps 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 uA9638 is characterized for operation from 0°C to 70°C.
