■ Output will not load line when V_CC = 0 V
■ Meets the requirements of EIA standard
RS-422
■ Operation from single 5 V supply
■ 3-state outputs for connection to system buses
■ Low quiescent current
■ Available in surface mount
Description
The ST26C31B 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 ST26C31B 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 V_CC and ground.
