74HC4851PW-Q100 from Nexperia, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Y4 bidirectional Independent analog input/output channel 4. Switched to common Z when E=L and S2:S0 = 100. RON ~76 Ω @ VCC=4.5 V.
2 Y6 bidirectional Independent analog input/output channel 6. Switched to common Z when E=L and S2:S0 = 110.
3 Z bidirectional Common analog input/output. Connects to the selected Yn channel when E is LOW.
4 Y7 bidirectional Independent analog input/output channel 7. Switched to common Z when E=L and S2:S0 = 111.
5 Y5 bidirectional Independent analog input/output channel 5. Switched to common Z when E=L and S2:S0 = 101.
6 E input Active-LOW enable input. When LOW, one Yn (selected by S0-S2) connects to Z. When HIGH, all switches are in high-impedance OFF-state.
7 NC unconnected Not connected. Leave floating or tie for board layout convenience.
8 GND power_in Ground reference (0 V).
9 S2 input Digital channel-select input, MSB of the 3-bit channel address (S2:S1:S0).
10 S1 input Digital channel-select input, middle bit of the 3-bit channel address.
11 S0 input Digital channel-select input, LSB of the 3-bit channel address.
12 Y3 bidirectional Independent analog input/output channel 3. Switched to common Z when E=L and S2:S0 = 011.
13 Y0 bidirectional Independent analog input/output channel 0. Switched to common Z when E=L and S2:S0 = 000.
14 Y1 bidirectional Independent analog input/output channel 1. Switched to common Z when E=L and S2:S0 = 001.
15 Y2 bidirectional Independent analog input/output channel 2. Switched to common Z when E=L and S2:S0 = 010.
16 VCC power_in Positive supply voltage. Operating range 2.0 V to 6.0 V (74HC4851-Q100). Absolute max +7.0 V.
