Working Principles

The 74LVTH125BQ,115 is designed to translate logic-level signals between different voltage domains. It uses a combination of CMOS and TTL technologies to achieve high-speed operation and low power consumption. The IC consists of four independent buffers with 3-state outputs. When the output enable (OE) pin is low, the outputs are enabled and reflect the input signals. When the OE pin is high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.
