DS34C87TMX

Drivers, Receivers, Transceivers Overview

The DS34C87TMX is a CMOS quad differential line driver designed for digital data transmission over balanced lines. It meets EIA standard RS-422 requirements while maintaining low power consumption. The device accepts TTL or CMOS input levels and translates them to RS-422 output levels. It operates from a single 5V supply with a voltage range of 4.5V to 5.5V. Typical propagation delay is 6 ns, and typical output skew is 0.5 ns. Quiescent current is 500 µA maximum at VCC = 5V. It features tri-state outputs and separate enable circuitry for each pair of drivers.
