DS26C31

The DS26C31 is a quad differential line driver designed for digital data transmission over balanced lines. The DS26C31T meets all the requirements of EIA standard RS-422 while retaining the low power characteristics of CMOS. The DS26C31M is compatible with EIA standard RS-422; however, one exception in test methodology is taken (Note 8). This enables the construction of serial and terminal interfaces while maintaining minimal power con- sumption.

The DS26C31 accepts TTLor CMOS input levels and trans- lates these to RS-422 output levels. This part uses special output circuitry that enables the drivers to power down with- out loading down the bus.

All inputs of DS26C31 are protected against damage due to electrostatic discharge by diodes to V_CCand ground.
