Overview
The AM26C32IDR, 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 recommendations 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. The AM26C32IDR is manufactured using a BiCMOS process, combining the high voltage and current capabilities of bipolar transistors with the low power consumption of CMOS transistors, thereby reducing power consumption while maintaining AC and DC performance.
