3 Description

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.
