CMOS QUAD 3-STATE DIFFERENTIAL LINE RECEIVER
1/10September 2002 SUPPLYVOLTAGE RANGE4.5VTO 5.5V MINIMUM DIFFERENTIAL INPUT VOLTAGE 200mV TYPICAL PROPAGATION DELAYS: 19ns TYPICAL INPUT HYSTERESIS: 60mV INPUT RESISTANCE 10KΩ OPEN INPUT FAIL SAFE FEATURE OPERATING TEMPERATURE RANGE
-40°C TO 85°C
DESCRIPTIONThe ST34C86isa 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 characteristicsof CMOS.
The ST34C86 has an input sensivityof 200mV
over the common mode input voltage rangeof
±7V. Hysteresisis provided to improve noise
margin and discourage output instabilityfor slowly
changing input waveforms. The ST34C86 internal
pull-up and pull-down resistors. prevent output
oscillation on unused channels. Separate enable
pins allow independent controlof receiver pairs.
The 3-STATE outputs have 6mA source and sink
capability.
