1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the
    device.  These are stress ratings only, and functional operation of the device at these or any other
    conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure
    to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values except differential input voltage are with respect to the network GND.
(3) Maximum power dissipation is a function of T_{J(max), JA}, and _TA. The maximum allowable power dissipation
     at any allowable ambient temperature is P_D = (T_J(max) T_A)/_JA. Selecting the maximum of 150 can
     affect reliability.
(4) The package thermal impedance is calculated in accordance with JESD 51-7.


Description

The AM26LV31E-EP 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 AM26LV31E-EP is characterized for operation from 55 to 105.
