HEF4016BT from Nexperia, in a SOP-14. 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	1Y	bidirectional	Switch 1 independent analog/digital I/O terminal Y. Bidirectional signal path to 1Z when 1E is HIGH; input voltage range 0 V to VDD.
2	1Z	bidirectional	Switch 1 independent analog/digital I/O terminal Z. Bidirectional signal path to 1Y when 1E is HIGH; input voltage range 0 V to VDD.
3	2Z	bidirectional	Switch 2 independent analog/digital I/O terminal Z. Bidirectional signal path to 2Y when 2E is HIGH; input voltage range 0 V to VDD.
4	2Y	bidirectional	Switch 2 independent analog/digital I/O terminal Y. Bidirectional signal path to 2Z when 2E is HIGH; input voltage range 0 V to VDD.
5	2E	input	Enable input for switch 2, active HIGH. Drive HIGH to close switch 2 (2Y-2Z conducting); LOW turns the switch OFF.
6	3E	input	Enable input for switch 3, active HIGH. Drive HIGH to close switch 3 (3Y-3Z conducting); LOW turns the switch OFF.
7	VSS	power_in	Ground reference (0 V). Analog switch signal levels are referenced to VSS; also serves as the substrate/negative supply return.
8	3Y	bidirectional	Switch 3 independent analog/digital I/O terminal Y. Bidirectional signal path to 3Z when 3E is HIGH; input voltage range 0 V to VDD.
9	3Z	bidirectional	Switch 3 independent analog/digital I/O terminal Z. Bidirectional signal path to 3Y when 3E is HIGH; input voltage range 0 V to VDD.
10	4Z	bidirectional	Switch 4 independent analog/digital I/O terminal Z. Bidirectional signal path to 4Y when 4E is HIGH; input voltage range 0 V to VDD.
11	4Y	bidirectional	Switch 4 independent analog/digital I/O terminal Y. Bidirectional signal path to 4Z when 4E is HIGH; input voltage range 0 V to VDD.
12	4E	input	Enable input for switch 4, active HIGH. Drive HIGH to close switch 4 (4Y-4Z conducting); LOW turns the switch OFF.
13	1E	input	Enable input for switch 1, active HIGH. Drive HIGH to close switch 1 (1Y-1Z conducting); LOW turns the switch OFF.
14	VDD	power_in	Positive supply voltage. Recommended operating range 3.0 V to 15.0 V (absolute max +18 V). Analog signal swing on nY/nZ is bounded by VSS and VDD.
