Detailed Description

The DS26C31TM is a quad differential line driver designed for digital data transmission over balanced lines. The DS26C31TM meets all the requirements of EIA standard RS-422 while retaining the low power characteristics of CMOS. The DS26C31TM is compatible with EIA standard RS-422. This enables the construction of serial and terminal interfaces while maintaining minimal power consumption. The DS26C31TM 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 DS26C31TM 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.
