Working Principles

The SN74LVC2G66QDCURQ1 is based on high-speed CMOS technology. It consists of two independent bilateral switches that can be controlled individually using the control inputs (A1, B1, A2, B2). When the control input is high, the corresponding switch is turned on, allowing the signal to pass through from the Y1 or Y2 output. Conversely, when the control input is low, the switch is turned off, isolating the input from the output.
