Overview
The AM26LV31IDR is a low-voltage, high-speed quadruple differential line driver produced by Texas Instruments. This device is part of the AM26LV31 series, which includes the AM26LV31C and AM26LV31I models. It is designed to meet or exceed the standards of TIA/EIA-422-B and ITU Recommendation V.11, but with a reduced supply-voltage range. The AM26LV31IDR is optimized for balanced-bus transmission at switching rates up to 32MHz and is particularly suited for driving balanced lines such as twisted-pair transmission lines. The device features 3-state outputs and is characterized by its ultra-low power consumption and high-speed operation.
