Overview
The AM26LV32EIDR is a low-voltage, high-speed quadruple differential line receiver produced by Texas Instruments. This device is designed to meet or exceed the standards of TIA/EIA-422-B and ITU Recommendation V.11, making it suitable for balanced bus transmission at switching rates up to 32 MHz. The AM26LV32EIDR features 3-state outputs, which allow direct connection to bus-organized systems, and includes internal fail-safe circuitry to prevent unknown voltage signals at the receiver outputs. It operates from a single 3.3-V power supply and is optimized for low power dissipation, making it ideal for various high-reliability applications.
