STANDARD RS-422 OPERATION FROM SINGLE 5V SUPPLY 3-STATE OUTPUTS FOR CONNECTION TO
SYSTEM BUSES LOW QUIESCENT CURRENT AVAILABLEIN SURFACE MOUNT
DESCRIPTIONTheST26C31is aquaddifferential linedriver
designed for digital data transmission over
balanced lines and meetsall the requirementsof
EIA standard RS-422 while retaining the low
power characteristicsof CMOS.
The ST26C31 accepts TTLor CMOS input levels
and translates theseto RS-422 output levels. This
part uses special outputs circuitry commontoall
four drivers. All outputs are protected against
damage dueto electrostatic dischargeby diodeto
VCC and ground.
