Working Principles

The 74VCXH162245TTR is a bidirectional level shifter that allows for voltage translation between two logic families. It operates by receiving input signals from one logic family and translating them to the appropriate voltage levels for the other logic family. The direction of data flow is controlled by the DIR pin. When the DIR pin is set to a specific logic level, the data is transmitted in that direction.
