DollaTek 3Pcs 74HC4051 8 Channel Mux Analog Multiplexer Selector Module

The 74HC4051 is an 8-channel analog multiplexer/demultiplexer with 3 digital selects (S0-S2), one active low enable (E), and 8 independent inputs/outputs (Y0-Y7) ) and a common input / output (Z). When E is low, one of the 8 switches will be selected by S0-S2 (low-impedance state). When E is high, all switches enter a high-impedance state, directly ignoring S0-S2. VCC and GND are the supply pins for the digital control terminals (S0-S2, E). The VCC to GND range of the 74HC4051 is 2.0V-10.0V. As a digital multiplexer/demultiplexer, the VEE will be connected to GND (typically grounded).
