DESCRIPTION
The ST34C86 is a quad differential li ne receiver
designed to meet the RS-422, RS-423, and
Federal Standard 1020 and 1030 for balanc ed
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 sourc e and sink
capability.
