Overview
The AM26C32QD, 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, up to 1000 meters, ensuring reliable and easy-to-use connections. The AM26C32QD is manufactured using a BiCMOS process, combining the high voltage and current capabilities of bipolar transistors with the low power consumption of CMOS transistors, reducing power consumption to about one-fifth that of the standard AM26LS32 while maintaining AC and DC performance.
