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 two drivers.
The MC34C87 is pin compatible with the MC3487.
All pins are protected against damage due to electrostatic discharges.
Maximum Power Supply Current: 3 mA
2000 V ESD Protection on the Inputs and the Outputs
TTL/CMOS Input Compatible
Typical Propagation Delay: 6 ns
Typical Output Skew: 1 ns
Meets VO = 6.0 V (and VO = – 0.25 V), VCC = 0 V, IO < 100
