Overview
The AM26LV31CNSR is a BiCMOS quadruple differential line driver produced by Texas Instruments. This device is designed to meet the requirements of TIA/EIA-422-B and ITU Recommendation V.11, but with a reduced supply-voltage range. It is optimized for balanced-bus transmission at high switching rates, making it suitable for applications requiring fast and reliable data transmission. The AM26LV31CNSR features 3-state outputs and is available in plastic small-outline (SOP-16) packages, offering both active-high and active-low enable inputs for flexible integration into various circuit designs.
