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.
This part uses special output circuitry that enables the individual drivers to power down without loading down the bus.
The MC34C87 also includes special circuitry which will set the outputs to a high impedance mode during power up or down, preventing spurious glitches.
Each enable pin controls tw...
