This chip is ideal for connecting more than one analog input/output to the Arduino ESP8266 (which supports only one analog port). For this purpose you connect GND+VCC as usual and... Pin Z to A0 / Y0-Y7 to up to 8 analog devices / S0-S2 to 3 digital ports on the Arduino (binary switching the analog ports 0-7) / E to LOW/GND to enable Switches (see datasheet). The description lacks the supply voltage VCC which is 2V up to 10V and the data sheet which you can find at http://www.farnell.com/datasheets/1645588.pdf
期待通り、電子材料に適した封筒に詰める
