Working Principles

The PI74FCT2245ATS is designed to act as a bidirectional buffer/line driver, facilitating the transfer of data between devices operating at different voltage levels and signal types. It utilizes tri-state outputs, allowing multiple devices to share a common bus without interfering with each other's signals.

When the Output Enable (OE) pin is active, the input data from one side is transferred to the corresponding output pins on the other side. The direction of data flow is determined by the logic levels applied to the OE pins. When the OE pin is inactive, the outputs are in a high-impedance state, effectively disconnecting them from the bus.

The PI74FCT2245ATS operates within a specified supply voltage range and can handle input and output signals within this range. It provides reliable and efficient data transfer with minimal propagation delay.
