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.
