  • The ST26C31B 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.

    Key Features

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