AM26LV32EIPWR

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 bus-organized 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, shorted fail-safe, and terminated fail-safe, a high state is produced at the respective output. This device is supported for partial-powerdown applications using |off. |off circuitry disables the outputs, preventing damaging current back-flow through the device when it is powered down.
