Pinout

Pin Name Type Function
1 A0 input Binary-weighted address input that, together with A1 and A2, selects which one of the mutually exclusive outputs Y0 to Y7 goes HIGH.
2 A1 input Binary-weighted address input that, together with A0 and A2, selects which one of the mutually exclusive outputs Y0 to Y7 goes HIGH.
3 A2 input Binary-weighted address input that, together with A0 and A1, selects which one of the mutually exclusive outputs Y0 to Y7 goes HIGH.
4 E1 input Active-LOW enable input; all outputs are forced LOW unless E1 and E2 are LOW and E3 is HIGH.
5 E2 input Active-LOW enable input; all outputs are forced LOW unless E1 and E2 are LOW and E3 is HIGH.
6 E3 input Active-HIGH enable input; must be HIGH (with E1 and E2 LOW) for the decoder outputs to be enabled.
7 Y7 output Active-HIGH decoder output; one of the eight mutually exclusive outputs.
8 GND power_in Ground reference (0 V).
9 Y6 output Active-HIGH decoder output; one of the eight mutually exclusive outputs.
10 Y5 output Active-HIGH decoder output; one of the eight mutually exclusive outputs.
11 Y4 output Active-HIGH decoder output; one of the eight mutually exclusive outputs.
12 Y3 output Active-HIGH decoder output; one of the eight mutually exclusive outputs.
13 Y2 output Active-HIGH decoder output; one of the eight mutually exclusive outputs.
14 Y1 output Active-HIGH decoder output; one of the eight mutually exclusive outputs.
15 Y0 output Active-HIGH decoder output; one of the eight mutually exclusive outputs.
16 VCC power_in Supply voltage; recommended operating range is 2.0 V to 6.0 V (4.5 V to 5.5 V for the 74HCT variant).
