MOTOROLA ANALOG IC DEVICE DATA
The Motorola AM26LS31 is a quad differential line driver intended for
digital data transmission over balanced lines. It meets all the requirements of
EIA–422 Standard and Federal Standard 1020.
The AM26LS31 provides an enable/disable function common to all four
drivers as opposed to the split enables on the MC3487 EIA–422 driver.
The high impedance output state is assured during power down.
Full EIA–422 Standard Compliance
Single +5.0 V Supply
Meets Full VO = 6.0 V, VCC = 0 V, IO
Output Short Circuit Protection
Complementary Outputs for Balanced Line Operation
