Overview
The AM26C32CDBR, produced by Texas Instruments, is a quadruple differential line receiver designed for balanced or unbalanced digital data transmission. This device is compliant with ANSI TIA/EIA-422-B, TIA/EIA-423-B, and ITU recommendations V.10 and V.11, making it suitable for a wide range of applications requiring reliable and high-integrity signal transmission.
The AM26C32CDBR is manufactured using a BiCMOS process, combining the high voltage and current capabilities of bipolar transistors with the low power consumption of CMOS transistors. This results in significantly reduced power consumption compared to the standard AM26LS32, while maintaining excellent AC and DC performance.
