The MC34C86 is a quad differential line receiver designed for digital data
transmission over balanced lines. The MC34C86 meets all the requirements of
standard EIA–422–A while retaining the low–power characteristics of CMOS.
The MC34C86 has an input sensitivity of 200 mV over the common mode
input voltage range of ± 7 V. In addition, each receiver chain has internal
hysteresis circuitry to improve noise margin and discourage output instability for
slowly changing input waveforms.

MAXIMUM RATINGS
Rating
This device contains circuitry to protect the
inputs against damage due to high static volt-
ages or electric fields; however, it is advised that
normal precautions be taken to avoid applica-
tions of any voltage higher than the maximum
rated voltages to this high impedance circuit.
For proper operation it is recommended that
