Overview
The AM26LS32AIDRG4 is a quadruple differential line receiver produced by Texas Instruments. This device is designed to meet or exceed 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 balanced and unbalanced digital data transmission in various applications. The AM26LS32AIDRG4 operates from a single 5-V supply and features low-power Schottky circuitry, making it suitable for power-sensitive designs. The device includes four independent receiver chains with three-state outputs, which can be connected directly to a bus-organized system. The fail-safe design ensures that the outputs are always high when the inputs are open, terminated, or shorted.
