Working Principles

The SN74ALVC125PW is designed to buffer and drive signals between different voltage domains. It operates by receiving input signals from one voltage domain and translating them to the appropriate voltage level for output to another voltage domain. The tri-state outputs allow bidirectional communication and facilitate bus sharing.

When the Output Enable (OE) pin is high, the outputs are enabled and actively driven according to the input signals. When OE is low, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.

The IC operates within a specified supply voltage range and provides reliable logic level translation while maintaining signal integrity.
