CMOS

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 i nternal
hysteresis circuitry to improve noise margin and discourage output instability for
slowly changing input waveforms.

The MC34C86 is pin compatible with the MC3486.

All pins are protected against damage due to electrostatic discharges.

• Typical Power Supply Current: 6 mA

• 2000 V ESD Protection on the Inputs and Outputs

• Typical Propagation Delay: 18 ns

• Typical Input Hysteresis: 75 mV

• Meets the Requirements of Standard EIA–422–A

• Operation from Single 5 V Supply

• High Impedance Mode for Outputs Connected to System Buses

• TTL/CMOS Compatible Outputs

NOTES:

1. All currents into device pins are shown as positive, out of device pins are negative. All voltages referenced to ground unless otherwise noted.

2. See EIA specifications EIA–422–A for exact test conditions.

This device contains circuitry to protect the
inputs against damage due to high static volt­ages or electric fields; however, it is advised that
normal precautions be taken to avoid applica­tions of any voltage higher than the maximum
rated voltages to this high impedance circuit.

For proper operation it is recommended that
Vin and V

out

be constrained to the range VSS ≤

(Vin or V

out

) ≤ VDD. Reliability of operation is
enhanced if unused inputs are tied to and
appropriate logic voltage level (e.g., either V

SS

or VDD).
