Working Principles

The SN74LVCZ245APWT is designed to facilitate bidirectional voltage level translation between different logic levels. It features two sets of 8-bit channels (A and B) that can be independently controlled using the DIR pin. When the DIR pin is set to logic high, data flows from channel A to channel B, and when set to logic low, data flows from channel B to channel A.

The OE pin is used to enable or disable the outputs. When OE is set to logic low, the outputs are enabled, allowing data to be transmitted. Conversely, when OE is set to logic high, the outputs are disabled, effectively isolating the device from the bus.
