Overview
The AM26LS32ACNSR, produced by Texas Instruments, is a quadruple differential line receiver 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. This device is optimized for balanced and unbalanced digital data transmission, making it suitable for a wide range of applications that require reliable and high-integrity signal transmission over long distances.
The AM26LS32ACNSR operates from a single 5-V supply and features low-power Schottky circuitry, which enhances its efficiency and reliability. It includes four independent receiver chains, each with three-state outputs and internal hysteresis to improve noise margin and stability. The device is also designed with fail-safe inputs, ensuring that the outputs remain high if the inputs are open, terminated, or shorted.
