Overview
The AM26C32, produced by Texas Instruments, is a quadruple differential line receiver designed for balanced or unbalanced digital data transmission. This device complies with the requirements of ANSI TIA/EIA-422-B, TIA/EIA-423-B, and ITU Recommendation 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 transistors. This results in a significant reduction in power consumption compared to the standard AM26LS32, while maintaining AC and DC performance. The AM26C32 allows low-power or low-voltage microcontrollers to interface with heavy machinery and other devices over long distances, up to 1000 meters, ensuring reliable and easy-to-use connections.
