CD4051S

GR · Analog Switches, Multiplexers · SOP-16

CD4051S from GR, in a SOP-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	4	passive	Analog channel 4 terminal of the 8-channel switch, selected when C-B-A = 100 and INH is low; analog range 0 to VDD-VEE.
2	6	passive	Analog channel 6 terminal of the 8-channel switch, selected when C-B-A = 110 and INH is low; analog range 0 to VDD-VEE.
3	COM	bidirectional	Common analog output/input terminal connected to whichever channel is selected; analog range 0 to VDD-VEE.
4	7	passive	Analog channel 7 terminal of the 8-channel switch, selected when C-B-A = 111 and INH is low; analog range 0 to VDD-VEE.
5	5	passive	Analog channel 5 terminal of the 8-channel switch, selected when C-B-A = 101 and INH is low; analog range 0 to VDD-VEE.
6	INH	input	Inhibit (enable control) input; when INH = VDD all channels are turned off, and recommended control input range is 0 to VDD-VSS.
7	VEE	power_in	Analog switch negative supply; recommended VDD-VEE is 0 V to 15 V and the absolute maximum VDD-VEE is 18 V.
8	VSS	power_in	Digital/power ground reference for the control inputs; recommended VDD-VSS is 3 V to 15 V and the absolute maximum DC supply VDD-VSS is -0.5 V to 18 V.
9	C	input	Binary channel select input (most significant bit of the channel address); control input range 0 to VDD-VSS.
10	B	input	Binary channel select input (middle bit of the channel address); control input range 0 to VDD-VSS.
11	A	input	Binary channel select input (least significant bit of the channel address); control input range 0 to VDD-VSS.
12	3	passive	Analog channel 3 terminal of the 8-channel switch, selected when C-B-A = 011 and INH is low; analog range 0 to VDD-VEE.
13	0	passive	Analog channel 0 terminal of the 8-channel switch, selected when C-B-A = 000 and INH is low; analog range 0 to VDD-VEE.
14	1	passive	Analog channel 1 terminal of the 8-channel switch, selected when C-B-A = 001 and INH is low; analog range 0 to VDD-VEE.
15	2	passive	Analog channel 2 terminal of the 8-channel switch, selected when C-B-A = 010 and INH is low; analog range 0 to VDD-VEE.
16	VDD	power_in	Positive digital supply; recommended VDD-VSS is 3 V to 15 V and the absolute maximum DC supply VDD-VSS is -0.5 V to 18 V.
