Overview
The AM26C32CDB, 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. It is manufactured using a BiCMOS process, combining the high voltage and current capabilities of bipolar transistors with the low power consumption of CMOS technology. This results in significantly reduced power consumption compared to standard devices like the AM26LS32, while maintaining excellent AC and DC performance.
