MC34C87 Overview
MOTOROLA SEMICONDUCTOR TECHNICAL DATA Product Preview Quad EIA-422-A Line Driver CMOS The MC34C87 is a quad differential line driver designed for digital data transmission over balanced lines. The MC34C87 meets all the requirements of standard EIA 422 A while retaining the low power characteristics of CMOS. The MC34C87 accepts TTL or CMOS input levels and translates these to EIA 422 A output level.
