74HC4067PW from Nexperia, in a TSSOP-24. 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	Z	bidirectional	Common analog input/output (the shared pole of the SP16T switch). Connects to whichever Y0..Y15 channel is selected by S0..S3 when E is LOW.
2	Y7	bidirectional	Independent analog input/output channel 7. Routed to Z when S3..S0 = 0111 and E is LOW.
3	Y6	bidirectional	Independent analog input/output channel 6. Routed to Z when S3..S0 = 0110 and E is LOW.
4	Y5	bidirectional	Independent analog input/output channel 5. Routed to Z when S3..S0 = 0101 and E is LOW.
5	Y4	bidirectional	Independent analog input/output channel 4. Routed to Z when S3..S0 = 0100 and E is LOW.
6	Y3	bidirectional	Independent analog input/output channel 3. Routed to Z when S3..S0 = 0011 and E is LOW.
7	Y2	bidirectional	Independent analog input/output channel 2. Routed to Z when S3..S0 = 0010 and E is LOW.
8	Y1	bidirectional	Independent analog input/output channel 1. Routed to Z when S3..S0 = 0001 and E is LOW.
9	Y0	bidirectional	Independent analog input/output channel 0. Routed to Z when S3..S0 = 0000 and E is LOW.
10	S0	input	Address input bit 0 (LSB) of the 4-bit channel-select bus. Together with S1..S3 selects which Y channel connects to Z. CMOS-level input on 74HC4067.
11	S1	input	Address input bit 1 of the 4-bit channel-select bus. CMOS-level input on 74HC4067.
12	GND	power_in	Ground reference (0 V) for the device.
13	S3	input	Address input bit 3 (MSB) of the 4-bit channel-select bus. CMOS-level input on 74HC4067.
14	S2	input	Address input bit 2 of the 4-bit channel-select bus. CMOS-level input on 74HC4067.
15	E	input	Active-LOW enable input. When LOW the selected switch is ON; when HIGH all 16 switches are OFF (device disabled). CMOS-level input on 74HC4067.
16	Y15	bidirectional	Independent analog input/output channel 15. Routed to Z when S3..S0 = 1111 and E is LOW.
17	Y14	bidirectional	Independent analog input/output channel 14. Routed to Z when S3..S0 = 1110 and E is LOW.
18	Y13	bidirectional	Independent analog input/output channel 13. Routed to Z when S3..S0 = 1101 and E is LOW.
19	Y12	bidirectional	Independent analog input/output channel 12. Routed to Z when S3..S0 = 1100 and E is LOW.
20	Y11	bidirectional	Independent analog input/output channel 11. Routed to Z when S3..S0 = 1011 and E is LOW.
21	Y10	bidirectional	Independent analog input/output channel 10. Routed to Z when S3..S0 = 1010 and E is LOW.
22	Y9	bidirectional	Independent analog input/output channel 9. Routed to Z when S3..S0 = 1001 and E is LOW.
23	Y8	bidirectional	Independent analog input/output channel 8. Routed to Z when S3..S0 = 1000 and E is LOW.
24	VCC	power_in	Positive supply voltage. Operating range 2.0 V to 10.0 V (74HC4067) or 4.5 V to 5.5 V (74HCT4067). Absolute maximum 11.0 V.
