Quad ELA-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.
