MOTOROLA MC26LS31D

Order this document by AM26LS31/D
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.
