Overview
The AM26LV32EIRGYRG4, produced by Texas Instruments, is a low-voltage, high-speed quadruple differential line receiver. This device is designed to meet 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 AM26LV32E features 3-state outputs, enabling direct connection to bus-organized systems. It operates from a single 3.3-V power supply and includes internal fail-safe circuitry to prevent unknown voltage signals at the receiver outputs.
