DESCRIPTION

TheST26C31 is aquaddifferential linedriver

designed

for

digital

data

transmission

over

balanced lines and meets all the requirements of

EIA standard RS-422 while retaining the low

power characteristics of CMOS.

The ST26C31 accepts TTL or CMOS input levels

and translates these to RS-422 output levels. This

part uses special outputs circuitry common to all

four drivers. All outputs are protected against

damage due to electrostatic discharge by diode to

VCC and ground.
