3 Description

The AM26LV32E device consists of quadruple

differential line receivers with 3-state outputs. This

device is designed to meet TIA/EIA-422-B and ITU

recommendation V.11 drivers with reduced supply

voltage. The device is optimized for balanced bus

transmission at switching rates up to 32 MHz. The

3-state outputs permit connection directly to a busorganized

system. The AM26LV32E has an internal

fail-safe circuitry that prevents the device from putting

an unknown voltage signal at the receiver outputs.

In the open fail-safe, a high state is produced at

the respective output. This device is supported for

partial-power-down applications using Ioff. Ioff circuitry

disables the outputs, preventing damaging current

back-flow through the device when it is powered

down.
