Overview
The Texas Instruments AM26LV32EIRGYR is a low-voltage, high-speed quadruple differential line receiver designed to meet the standards of TIA/EIA-422-B and ITU recommendation V.11. This device operates from a single 3.3-V power supply and is optimized for balanced bus transmission at switching rates up to 32 MHz. It features 3-state outputs, allowing direct connection to bus-organized systems, and includes internal fail-safe circuitry to prevent unknown voltage signals at the receiver outputs. The AM26LV32EIRGYR is suitable for various communication interfaces such as RS-485, PROFIBUS, and CAN bus systems due to its high-speed data transmission, low power consumption, and robustness against electromagnetic interference.
