Working Principles

The 74FCT16245CTPVCTG4 operates based on the principles of voltage level translation and bidirectional data transfer. It utilizes a combination of input/output buffers, direction control, and output enable functionality to facilitate seamless communication between two buses with different voltage levels.

When the DIR pin is set to a specific logic level, the direction of data flow is determined. The OE pin enables or disables the output buffers, allowing control over when data is transmitted/received. The internal circuitry ensures proper voltage level translation, maintaining signal integrity during data
