FAQ

What is the maximum input voltage tolerance for the 74ALVC374D?

The inputs are overvoltage tolerant up to 5.5 V, allowing safe interfacing with 5 V logic devices even when the device is powered at 3.3 V.

How does the 3-state output function work on this device?

When the Output Enable (OE) pin is HIGH, the outputs assume a high-impedance OFF-state, effectively disconnecting them from the bus regardless of the stored data state.
