Working Principles

The SN74ABTR2245PWG4 is an octal bus transceiver that allows bidirectional data transfer between two independent buses. It features non-inverting outputs, which means the data received on one bus is transmitted as-is to the other bus. The output enable control pin enables or disables the transceiver, providing bus isolation when needed.

The device operates within a specified supply voltage range and can handle input/output voltages up to the supply voltage. It has a fast propagation delay, ensuring quick data transfer between the buses. Additionally, it incorporates ESD protection to safeguard against electrostatic discharge, enhancing its reliability.
