Working Principles

The SN74LVCZ245APWR is designed to facilitate the bidirectional translation of signals between two voltage domains. It utilizes a combination of MOSFETs and CMOS technology to achieve this functionality. The DIR pin controls the direction of data flow, while the OE pin enables or disables the outputs.

When the DIR pin is set to a specific logic level, the IC will translate the input signals from one voltage domain to the other. The OE pin can be used to enable or disable the outputs, allowing for easy control of the data transmission.
