Quad EIA-422-A Line Driver
CMOS
The MC26C31 is a quad differential line driver designed for digital data
transmission over balanced lines. The MC26C31 meets all the requirements of
standard EIA–422–A while retaining the low–power characteristics of CMOS.
The MC26C31 accepts TTL or CMOS input levels and translates these to
EIA–422–A output level. This part uses special output circuitry that enables the
individual drivers to power down without loading down the bus. The MC26C31
also includes special circuitry which will set the outputs to a high impedance
mode during power up or down, preventing spurious glitches. This device has
enable and disable circuitry common for all four drivers.
The MC26C31 is pin compatible with the AM26LS31.
All pins are protected against damage due to electrostatic discharges.
• Maximum Supply Current: 3 mA
• 2000 V ESD Protection on the Inputs and Outputs
• TTL/CMOS Input Compatible
• Typical Propagation Delay: 6 ns
• Typical Output Skew: 1 ns
• Meets VO = 6.0 V (and VO = 0.25 V), VCC = 0 V, IO < 100 µA Requirement
• Meets the Requirements of Standard EIA–422–A
• Operation from Single 5 V Supply
• High Impedance Mode for Outputs Connected to System Buses
