HEF4051BTT 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 that connects to Z when selected by S1 to S3 with E LOW; Yn and Z voltages must not exceed VDD or VEE, and the input/output current is limited to ±10 mA.
2 Y6 bidirectional Independent analog input/output channel 6 that connects to Z when selected by S1 to S3 with E LOW; Yn and Z voltages must not exceed VDD or VEE, and the input/output current is limited to ±10 mA.
3 Z bidirectional Common analog output or input of the 8-channel switch; voltages at Z must not exceed VDD or VEE, and the input/output current is limited to ±10 mA.
4 Y7 bidirectional Independent analog input/output channel 7 that connects to Z when selected by S1 to S3 with E LOW; Yn and Z voltages must not exceed VDD or VEE, and the input/output current is limited to ±10 mA.
5 Y5 bidirectional Independent analog input/output channel 5 that connects to Z when selected by S1 to S3 with E LOW; Yn and Z voltages must not exceed VDD or VEE, and the input/output current is limited to ±10 mA.
6 E input Active-LOW enable input; a HIGH level switches all channels off, and the input clamp current for this pin is limited to ±10 mA when the input is below VSS - 0.5 V or above VDD + 0.5 V.
7 VEE power_in Supply voltage pin referenced to VDD, with a limiting value range of -18 V to +0.5 V.
8 VSS power_in Ground supply pin; all voltages in the datasheet are referenced to VSS = 0 V (ground).
9 S3 input Digital select input (binary channel select, S3 is the most significant bit of S3 S2 S1); the input voltage must stay between -0.5 V and VDD + 0.5 V, with input clamp current limited to ±10 mA.
10 S2 input Digital select input (binary channel select, S2 is the middle bit of S3 S2 S1); the input voltage must stay between -0.5 V and VDD + 0.5 V, with input clamp current limited to ±10 mA.
11 S1 input Digital select input (binary channel select, S1 is the least significant bit of S3 S2 S1); the input voltage must stay between -0.5 V and VDD + 0.5 V, with input clamp current limited to ±10 mA.
12 Y3 bidirectional Independent analog input/output channel 3 that connects to Z when selected by S1 to S3 with E LOW; Yn and Z voltages must not exceed VDD or VEE, and the input/output current is limited to ±10 mA.
13 Y0 bidirectional Independent analog input/output channel 0 that connects to Z when selected by S1 to S3 with E LOW; Yn and Z voltages must not exceed VDD or VEE, and the input/output current is limited to ±10 mA.
14 Y1 bidirectional Independent analog input/output channel 1 that connects to Z when selected by S1 to S3 with E LOW; Yn and Z voltages must not exceed VDD or VEE, and the input/output current is limited to ±10 mA.
15 Y2 bidirectional Independent analog input/output channel 2 that connects to Z when selected by S1 to S3 with E LOW; Yn and Z voltages must not exceed VDD or VEE, and the input/output current is limited to ±10 mA.
16 VDD power_in Positive supply voltage, recommended 3 V to 15 V (absolute limiting range -0.5 V to +18 V referenced to VSS).
