The DS26C31TM/NOPB is a CMOS quad Tri-state Differential Line Driver designed for digital data transmission over balanced lines. It meets all the requirements of EIA standard RS-422 while retaining the low power characteristics of CMOS. The DS26C31TM/NOPB 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. It 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.
