Product Highlight

  • Supply Voltage: 4.5 to 5.5 V
  • Operating Temp Range: -40 to +85 °C
The ST26C31BDR is a quad differential line driver designed for digital data transmission over balanced lines and meets all the requirements of EIA standard RS-422 while retaining the low power characteristics of CMOS. The ST26C31B accepts TTL or CMOS input levels and translates these to RS-422 output levels.

This part uses special outputs circuitry common to all four drivers. All outputs are protected against damage due to electrostatic discharge by diode to VCC and ground.


  • TTL input compatible
  • Typical propagation delay: 6 ns
  • Typical output skew: 0.5 ns
  • Output will not load line when VCC = 0 V
  • Meets the requirements of EIA standard RS-422
  • Operation from single 5 V supply
  • 3-state outputs for connection to system buses
  • Low quiescent current
  • Available in surface mount
