Working Principles

The MC74LVX245DTR2G is a level shifter/transceiver integrated circuit that facilitates the translation of digital signals between different voltage domains. It operates bidirectionally, allowing data to be transferred from one voltage domain to another without any inversion.

The device features non-inverting outputs, which means that the logic levels of the input signals are maintained in the output signals. This characteristic is particularly useful when interfacing between systems with different voltage levels.

The MC74LVX245DTR2G also includes 3-state outputs, which enable multiple devices to share a common bus. When the output enable (OE#) pin is high, the outputs are in a high-impedance state, allowing other devices to drive the bus.
