74HC4851PW from Nexperia, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Y4 | bidirectional | Independent analog input/output channel 4; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH. |
| 2 | Y6 | bidirectional | Independent analog input/output channel 6; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH. |
| 3 | Z | bidirectional | Common analog input/output; connected to the selected Yn channel when E is LOW. |
| 4 | Y7 | bidirectional | Independent analog input/output channel 7; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH. |
| 5 | Y5 | bidirectional | Independent analog input/output channel 5; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH. |
| 6 | E | input | Enable input, active LOW; when HIGH all switches are in the high-impedance OFF-state independent of S0 to S2. |
| 7 | n.c. | unconnected | Not connected. |
| 8 | GND | power_in | Ground (0 V) reference for all voltages on the device. |
| 9 | S2 | input | Select input (most significant bit of the channel select code); with S1 and S0 chooses which Yn channel connects to Z when E is LOW. |
| 10 | S1 | input | Select input (middle bit of the channel select code); with S2 and S0 chooses which Yn channel connects to Z when E is LOW. |
| 11 | S0 | input | Select input (least significant bit of the channel select code); with S2 and S1 chooses which Yn channel connects to Z when E is LOW. |
| 12 | Y3 | bidirectional | Independent analog input/output channel 3; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH. |
| 13 | Y0 | bidirectional | Independent analog input/output channel 0; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH. |
| 14 | Y1 | bidirectional | Independent analog input/output channel 1; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH. |
| 15 | Y2 | bidirectional | Independent analog input/output channel 2; connects to common Z when selected by S0 to S2 with E LOW, and is high-impedance OFF when E is HIGH. |
| 16 | VCC | power_in | Supply voltage: recommended 2.0 V to 6.0 V for 74HC4851 and 4.5 V to 5.5 V for 74HCT4851; absolute maximum VCC is 7.0 V. |
