Working Principles

The 74ALVC125PW-Q100J operates by receiving input signals on the A1-A4 pins and providing buffered output signals on the Y1-Y4 pins. The output enable (OE) pins control the 3-state outputs, allowing the IC to be enabled or disabled as needed. When the OE pin is high, the outputs are active, and when it is low, the outputs are in a high-impedance state.

The IC performs voltage level shifting by accepting inputs at one voltage level and providing outputs at a different voltage level. This feature enables seamless communication between devices operating at different voltage domains.
