AM26LV31E-EP Enhanced Product Low-Voltage High-Speed Quad Differential Line Driver, +/-15-kV IEC ESD Protection |

AM26LV31E-EP (ACTIVE) Enhanced Product Low-Voltage High-Speed Quad Differential Line Driver, +/-15-kV IEC ESD Protection



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 AM26LV31ES is characterized for operation from –55°C to 105°C.
