Working Principles

The PI74FCT162245CTVEX is a bidirectional buffer/level shifter IC that allows for the transfer of digital signals between different voltage domains. It features separate input/output ports (A, B, C, D, and E) and can be controlled using the OE (Output Enable) and DIR (Direction) pins.

When the OE pin is low, the outputs are enabled, allowing data to be transferred bidirectionally between the ports. The DIR pin determines the direction of data flow. When DIR is high, data flows from ports A to E, and when DIR is low, data flows from ports E to A.

The IC operates on a supply voltage range of 4.5V to 5.5V and provides ESD protection of over 2000V. It offers high-speed operation with minimal propagation delay, making it suitable for applications requiring fast data transfer.
