Overview
The AM26LV31EIPWRG4, produced by Texas Instruments, is a low-voltage, high-speed quadruple differential line driver. This device is designed to meet the standards of TIA/EIA-422-B and ITU Recommendation V.11 with reduced supply voltage. It operates from a single 3.3V power supply and is optimized for balanced-bus transmission at switching rates up to 32MHz. The AM26LV31E features 3-state outputs and provides high current capability for driving balanced lines, such as twisted-pair transmission lines, while maintaining high impedance in the power-off condition. The device is characterized for operation from –40°C to +85°C and includes robust ESD protection.
