TEXAS INSTRUMENTS AM26LV32EMDREP

The AM26LV32EMDREP is a quad low-voltage high-speed differential Line Receiver with 3-state outputs. This differential receiver has ±15kV ESD (HBM and IEC61000-4-2, air-gap discharge) and ±8kV ESD (IEC61000-4-2, contact discharge) protection for RS422 bus pins. This device is designed to meet TIA/EIA-422-B and ITU recommendation V.11 driver with reduced supply voltage. The device is optimized for balanced bus transmission at switching rates up to 32MHz. The 3-state outputs permit connection directly to a bus-organized system. It 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-power-down applications using IOFF. IOFF circuitry disables the outputs, preventing damaging current backflow-through the device when it is powered down.
