Working Principles

The SN74CBT1G125DBVT is a single-bit bus switch that allows bidirectional level shifting between two voltage domains. It operates by controlling the flow of data between the input/output pins A and B. The output enable (OE) pin determines whether the output pin (Y) is active or in a high-impedance state.

When OE is low, the switch is enabled, and the input signal at pin A is transmitted to pin B. Conversely, when OE is high, the switch is disabled, and pin B is isolated from pin A. This bidirectional functionality enables seamless communication between different voltage levels.
