DESCRIPTION
The ST26C31 is a quad differential line driver
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.
