Overview
The AM26C32IDRE4, produced by Texas Instruments, is a quadruple differential line receiver designed for balanced or unbalanced digital data transmission. This device meets or exceeds the requirements of ANSI TIA/EIA-422-B, TIA/EIA-423-B, and ITU Recommendation V.10 and V.11. It is particularly useful for interfacing low-power or low-voltage microcontrollers with heavy machinery, subsystems, and other devices over long distances of up to 1000 meters, ensuring reliable and easy-to-use connections.
The AM26C32IDRE4 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 AC and DC performance.
