3 1A1 input Binary weighted address input for first 2-to-4 decoder.
4 1Y0 output Active LOW output of first 2-to-4 decoder.
5 1Y1 output Active LOW output of first 2-to-4 decoder.
6 1Y2 output Active LOW output of first 2-to-4 decoder.
7 1Y3 output Active LOW output of first 2-to-4 decoder.
8 GND power_in Ground (0 V).
9 2Y3 output Active LOW output of second 2-to-4 decoder.
10 2Y2 output Active LOW output of second 2-to-4 decoder.
11 2Y1 output Active LOW output of second 2-to-4 decoder.
12 2Y0 output Active LOW output of second 2-to-4 decoder.
13 2A1 input Binary weighted address input for second 2-to-4 decoder.
14 2A0 input Binary weighted address input for second 2-to-4 decoder.
15 2E input Enable input (active LOW) for second decoder; all outputs forced HIGH when this pin is HIGH.
16 VCC power_in Positive supply voltage; recommended minimum 2.0 V, typical 5.0 V, maximum 6.0 V.
