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 I

off

. I

off

circuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down.

The AM26LV32EI is characterized for operation from –40°C to 85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
