DESCRIPTION

The ST34C86 is a quad differential line receiver

designed to meet the RS-422, RS-423, and

Federal Standard 1020 and 1030 for balanced

and unbalanced digital data transmission, while

retaining the low power characteristics of CMOS.

The ST34C86 has an input sensivity of 200mV

over the common mode input voltage range of

±7V. Hysteresis is provided to improve noise

margin and discourage output instability for slowly

changing input waveforms. The ST34C86 internal

pull-up and pull-down resistors. prevent output

oscillation on unused channels. Separate enable

pins allow independent control of receiver pairs.

The 3-STATE outputs have 6mA source and sink

capability.
