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 Vout be constrained to the range V_SS 3 (V_in or V_out) 3 V_DD. Reliability of operation is enhanced if unused inputs are tied to and appropriate logic voltage level (e.g., either V_SS or V_DD)



Description

The MC26C32 is a quad differential line receiver designed for digital data transmission over balanced lines. The MC26C32 meets all the requirements of standard EIA422A while retaining the lowpower characteristics of CMOS.

The MC26C32 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.

The MC26C32 is pin compatible with the AM26LS32.

All pins are protected against damage due to electrostatic discharges.
