Working Principles

The 74LVCH16245APAG is designed to perform voltage level shifting and bus transceiving functions. It utilizes a combination of MOSFETs and CMOS technology to achieve bidirectional signal translation between different logic levels. The inputs and outputs are non-inverting, allowing for direct interfacing with various logic families.

The device operates by monitoring the input voltage levels and translating them to the corresponding output voltage levels based on the supply voltage applied. When the output is not required, the tri-state feature allows the outputs to be effectively disconnected from the bus, preventing any interference or contention.
