AM26LV32EIDR

Product Summary

The AM26LV32EIDR is a quadruple differential line receiver with 3-state outputs. The differential receiver has ±15-kV ESD (HBM and IEC61000-4-2, Air-Gap Discharge) and ±8-kV ESD (IEC61000-4-2, Contact Discharge) protection for RS422 bus pins. The AM26LV32EIDR 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 AM26LV32EIDR 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. The AM26LV32EIDR is characterized for operation from –40℃ to 85℃.
