Working Principles
The SN74CB3T3125PWG4 is a 4-bit bus switch that allows bidirectional signal transmission between four independent buses. It operates by controlling the state of its internal switches based on the input signals and the output enable control. When the output enable (OE#) is active, the switch is enabled, allowing signals to pass through. Conversely, when the OE# is inactive, the switch is disabled, isolating the buses from each other.
