The AM26LV31E is a quadruple differential line driver with 3-state outputs. This driver has ±15kV ESD (HBM and IEC61000-4-2, Air-Gap Discharge) and ±8kV 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 32MHz. 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.
