Working Principles

The 74CBTLV3125DBQRG4 operates by controlling the flow of signals between its input and output pins. When the enable pin (OE#) is low, the switch is turned on, allowing signals to pass through from the input pins (A1, A2, B1, B2) to the output pin (Y1). Conversely, when the enable pin is high, the switch is turned off, isolating the input and output pins.
