Overview
The AM26LV32CDR, produced by Texas Instruments, is a low-voltage, high-speed quadruple differential line receiver. This device is designed to operate in accordance with the TIA/EIA-422-B and ITU Recommendation V.11 standards, but with a reduced common-mode voltage range due to its lower supply voltage. It is optimized for balanced bus transmission and features 3-state outputs, making it suitable for direct connection to bus-organized systems. The AM26LV32CDR is particularly useful in applications requiring reliable and high-speed data transmission over long distances.
