74LVC4245AD

Octal dual supply translating transceiver; 3-state

The 74LVC4245A is an octal dual supply translating transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. It is designed to interface between a 3 V and 5 V bus in a mixed 3 V and 5 V supply environment.

The device features an output enable input (pin OE) for easy cascading and a send/receive input (pin DIR) for direction control. Pin OE controls the outputs so that the buses are effectively isolated.

In suspend mode, when VCC(A) is zero, there will be no current flow from one supply to the other supply. The A-outputs must be set 3-state and the voltage on the A-bus must be smaller than Vdiode (typical 0.7 V).

VCC(A) ≥ VCC(B), except in suspend mode.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
