●The DS26C31TM is a CMOS Quad TRI-STATE Differential Line Driver, designed for digital data transmission over balanced lines. Meets all the requirements of EIA standard RS-422 while retaining the low power characteristics of CMOS. 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. 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.
● TTL input compatible
● 6ns Typical propagation delays
● 0.5ns Typical output skew
● Outputs will not load line when VCC = 0V
● DS26C31T Meets requirements of EIA standard RS-422
● Operation from single 5V supply
● Tri-state outputs for connection to system buses
● Low quiescent current
● Available in surface mount
● MIL-STD-883C compliant
●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
