Overview
The AM26LV31CDRE4, produced by Texas Instruments, is a BiCMOS quadruple differential line driver with 3-state outputs. This device is designed to be similar to TIA/EIA-422-B and ITU Recommendation V.11 drivers but operates with a reduced supply-voltage range. It is optimized for balanced-bus transmission at high switching rates and is particularly suited for applications requiring low power consumption without compromising speed, thanks to Texas Instruments' proprietary LinIMPACT-C60™ technology.
