The DS26C31 is a quad differential line driver designed for digital data transmission
over balanced lines. The DS26C31 meets all the requirements of EIA standard RS-422 while retaining
the low power characteristics of CMOS. The DS26C31 is compatible with EIA standard RS-422; however,
one exception in test methodology is taken. This enables the construction of serial and terminal
interfaces while maintaining minimal power consumption.
The DS26C31 accepts TTL or CMOS input levels and translates these to RS-422 output
levels. This part uses special output circuitry that enables the drivers to power down without
loading down the bus. This device has enable and disable circuitry common to all four drivers. The
DS26C31 is pin compatible to the AM26LS31 and the DS26LS31.
All inputs are protected against damage due to electrostatic discharge by diodes to
VCC and ground.
