Overview
The AM26LV31CDR is a BiCMOS quadruple differential line driver produced by Texas Instruments. It is designed to be similar to TIA/EIA-422-B and ITU Recommendation V.11 drivers but with a reduced supply-voltage range. This device is optimized for balanced-bus transmission at switching rates up to 32 MHz and features 3-state outputs. The AM26LV31CDR is characterized for operation from 0°C to 70°C and is manufactured using Texas Instruments' proprietary LinIMPACT-C60™ technology, which facilitates ultra-low power consumption without compromising speed.
