DESCRIPTION/ORDERING INFORMATION
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.
