Transcription

1 Dual 4-channel analog multiplexer / demultiplexer U402C / U402CF / U402CF The U402C, U402CF, and U402CF are multiplexers / demultiplexers capable of selecting and combining analog signals and digital signals with a configuration of 4 ch 2. Inhibit signals and control signals are used to turn on the switch of the corresponding channel. In addition, even if the logical amplitude (-SS) of the control signal is low, signals with a large amplitude (-) can be switched. In addition, as each switch has a low ON resistance, it can be connected to a low impedance circuit. lock diagram Y0 6 Y2 2 X2 Y0 Y 3 Y3 4 Y2 X2 Y X Y3 X 4 3 X X Y Y X0 X3 2 X X3 SS 8
