Working Principles
The SN74CBT3125CDR operates by selectively connecting one of the two inputs (A1/A2, A3/A4, B1/B2, or B3/B4) to the corresponding output (Y1, Y2, Y3, or Y4) based on the control signals applied to the OE# (Output Enable) pin. When OE# is low, the selected input is connected to the output, allowing signal transmission. When OE# is high, all outputs are in a high-impedance state, isolating them from the inputs.
