Overview
The AM26LV32EINSR 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 AM26LV32EINSR operates from a single 3.3-V power supply and features ultra-low power dissipation, typically 27 mW. It is optimized for high-speed data transmission and includes internal fail-safe circuitry to prevent unknown voltage signals at the receiver outputs in case of open circuits.
