Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I3 | input | Binary data input I3 of the 8-input multiplexer, routed to Y when selected by S2-S0. |
| 2 | I2 | input | Binary data input I2 of the 8-input multiplexer, routed to Y when selected by S2-S0. |
| 3 | I1 | input | Binary data input I1 of the 8-input multiplexer, routed to Y when selected by S2-S0. |
| 4 | I0 | input | Binary data input I0 of the 8-input multiplexer, routed to Y when selected by S2-S0. |
| 5 | Y | output | Multiplexer output, the selected data input in non-inverting form; forced LOW when E̅ is HIGH. |
| 6 | Y̅ | output | Complementary multiplexer output, forced HIGH when E̅ is HIGH. |
| 7 | E̅ | input | Enable input, active LOW; a HIGH on this pin forces output Y LOW and output Y̅ HIGH. |
| 8 | GND | power_in | Ground (0 V) reference for all voltages in the datasheet. |
| 9 | S2 | input | Common data select input, most significant bit of the 3-bit input select code. |
| 10 | S1 | input | Common data select input, middle bit of the 3-bit input select code. |
| 11 | S0 | input | Common data select input, least significant bit of the 3-bit input select code. |
| 12 | I7 | input | Binary data input I7 of the 8-input multiplexer, routed to Y when selected by S2-S0. |
| 13 | I6 | input | Binary data input I6 of the 8-input multiplexer, routed to Y when selected by S2-S0. |
| 14 | I5 | input | Binary data input I5 of the 8-input multiplexer, routed to Y when selected by S2-S0. |
| 15 | I4 | input | Binary data input I4 of the 8-input multiplexer, routed to Y when selected by S2-S0. |
| 16 | VCC | power_in | Supply voltage; recommended range 2.0 V to 6.0 V (typical 5.0 V), absolute maximum -0.5 V to +7.0 V. |
