Overview
The AM26C32CDE4, produced by Texas Instruments, is a quadruple differential line receiver designed for balanced or unbalanced digital data transmission. This device complies with or exceeds the requirements of ANSI TIA/EIA-422-B, TIA/EIA-423-B, and ITU recommendations V.10 and V.11. It operates from a single 5-V supply and features low power consumption, with a typical quiescent supply current of 10 mA. The AM26C32CDE4 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 makes it an efficient and reliable choice for various high-reliability applications.
