The AM26LV31E is a quadruple differential line driver with 3-state outputs. This driver has ± 15-kV ESD

(HBM and IEC61000-4-2, Air-Gap Discharge) and ± 8-kV ESD (IEC61000-4-2, Contact Discharge) protection.

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 outputs have high

current capability for driving balanced lines, such as twisted-pair transmission lines, and provide a high

impedance in the power-off condition.

The AM26LV31EI 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.
