74VHC4053AFT from TOSHIBA, in a TSSOP-16-175mil. 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	Y-switch channel 1 analog I/O (independent end). Connected to Y-COM when A=1 and INH=0. Signal range 0 to V_CC.
2	0Y	bidirectional	Y-switch channel 0 analog I/O (independent end). Connected to Y-COM when A=0 and INH=0. Signal range 0 to V_CC.
3	1Z	bidirectional	Z-switch channel 1 analog I/O (independent end). Connected to Z-COM when C=1 and INH=0. Signal range 0 to V_CC.
4	Z-COM	bidirectional	Z-switch common analog I/O (pole end). Routed to 0Z or 1Z based on select input C (INH must be low).
5	0Z	bidirectional	Z-switch channel 0 analog I/O (independent end). Connected to Z-COM when C=0 and INH=0. Signal range 0 to V_CC.
6	INH	input	Active-high inhibit. When high, all three switches are turned OFF regardless of A/B/C. CMOS logic input, V_IH ≥ 2.0 V at V_CC = 3.0 V.
7	GND	power_in	Ground / negative supply reference. Also sets the lower bound of the analog switch signal range.
8	GND	power_in	Ground / negative supply reference (second GND pin). Tie to the same ground plane as pin 7.
9	C	input	Select input C for the Z-switch. Selects 0Z (C=0) or 1Z (C=1) when INH is low.
10	B	input	Select input B for the X-switch. Selects 0X (B=0) or 1X (B=1) when INH is low.
11	A	input	Select input A for the Y-switch. Selects 0Y (A=0) or 1Y (A=1) when INH is low.
12	0X	bidirectional	X-switch channel 0 analog I/O (independent end). Connected to X-COM when B=0 and INH=0. Signal range 0 to V_CC.
13	1X	bidirectional	X-switch channel 1 analog I/O (independent end). Connected to X-COM when B=1 and INH=0. Signal range 0 to V_CC.
14	X-COM	bidirectional	X-switch common analog I/O (pole end). Routed to 0X or 1X based on select input B (INH must be low).
15	Y-COM	bidirectional	Y-switch common analog I/O (pole end). Routed to 0Y or 1Y based on select input A (INH must be low).
16	VCC	power_in	Positive supply, 2.0 to 5.5 V operating. Also sets the upper bound of the analog switch signal range. Decouple with a 0.1 µF ceramic close to the pin.
