74HCT4851BQ-Q100 from Nexperia, in a DHVQFN-16-EP(2.5x3.5). 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 of the 8-channel switch; switch voltage must stay within 0 V to VCC (absolute limit VCC + 0.5 V and -0.5 V). |
| 2 | Y6 | bidirectional | Independent analog input/output channel 6 of the 8-channel switch; switch voltage must stay within 0 V to VCC (absolute limit -0.5 V to VCC + 0.5 V). |
| 3 | Z | bidirectional | Common analog input/output that connects to the selected Yn channel when E is LOW; switch voltage must stay within 0 V to VCC (absolute limit -0.5 V to VCC + 0.5 V). |
| 4 | Y7 | bidirectional | Independent analog input/output channel 7 of the 8-channel switch; switch voltage must stay within 0 V to VCC (absolute limit -0.5 V to VCC + 0.5 V). |

| 9 | S2 | input | Select input, most significant bit of the channel address (with E LOW, S2 S1 S0 choose Y0 to Y7 per the function table); input voltage must stay within 0 V to VCC. |
| 10 | S1 | input | Select input, middle bit of the channel address (with E LOW, S2 S1 S0 choose Y0 to Y7 per the function table); input voltage must stay within 0 V to VCC. |
| 11 | S0 | input | Select input, least significant bit of the channel address (with E LOW, S2 S1 S0 choose Y0 to Y7 per the function table); input voltage must stay within 0 V to VCC. |
| 12 | Y3 | bidirectional | Independent analog input/output channel 3 of the 8-channel switch; switch voltage must stay within 0 V to VCC (absolute limit -0.5 V to VCC + 0.5 V). |
| 13 | Y0 | bidirectional | Independent analog input/output channel 0 of the 8-channel switch; switch voltage must stay within 0 V to VCC (absolute limit -0.5 V to VCC + 0.5 V). |
| 14 | Y1 | bidirectional | Independent analog input/output channel 1 of the 8-channel switch; switch voltage must stay within 0 V to VCC (absolute limit -0.5 V to VCC + 0.5 V). |
| 15 | Y2 | bidirectional | Independent analog input/output channel 2 of the 8-channel switch; switch voltage must stay within 0 V to VCC (absolute limit -0.5 V to VCC + 0.5 V). |
| 16 | VCC | power_in | Supply voltage: recommended 2.0 V to 6.0 V for 74HC4851-Q100 and 4.5 V to 5.5 V for 74HCT4851-Q100; absolute maximum -0.5 V to +7.0 V. |
