Overview
The AM26LV32CNSR, produced by Texas Instruments, is a BiCMOS, quadruple differential line receiver with 3-state outputs. This device is designed to meet the standards of TIA/EIA-422-B and ITU Recommendation V.11, with adaptations for reduced supply voltage. It is optimized for balanced bus transmission at switching rates up to 32 MHz, making it suitable for high-speed data transmission applications. The device features an enable function common to all four receivers, offering a choice of active-high or active-low inputs, and 3-state outputs that allow direct connection to a bus-organized system.
