Overview
The AM26LV32CDRE4, 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, but with a reduced common-mode voltage range due to its lower 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, allowing for active-high or active-low input configurations. The 3-state outputs enable direct connection to a bus-organized system, and each receiver has high input impedance and input hysteresis for enhanced noise immunity.
