DESCRIPTION/ORDERING INFORMATION
The AM26LV32E consists of quadruple differential line receivers with 3-state outputs. These differential receivers
have ±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.
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-power-down applications using Ioff. Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
The AM26LV32EM is characterized for operation from –55°C to 125°C.
