CD4051BE

HGSEMI · Analog Switches, Multiplexers · DIP-16

CD4051BE from HGSEMI, in a DIP-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 switch channel 4 terminal, connected to COM when addressed by A/B/C with INH low.
2	6	passive	Analog switch channel 6 terminal, connected to COM when addressed by A/B/C with INH low.
3	COM	bidirectional	Common channel terminal (OUT/IN); recommended analog input/output voltage is 0 to VDD-VEE V.
4	7	passive	Analog switch channel 7 terminal, connected to COM when addressed by A/B/C with INH low.
5	5	passive	Analog switch channel 5 terminal, connected to COM when addressed by A/B/C with INH low.
6	INH	input	Inhibit (enable control): when INH is high (VDD) all channels are off; when low, the channel selected by C, B, A is on.
7	VEE	power_in	Analog switch negative supply; recommended VDD-VEE is 0 to 15 V and the analog supply limit is 18 V.
8	VSS	power_in	Digital ground/reference pin; recommended VDD-VSS is 3 to 15 V and absolute maximum DC supply VDD-VSS is -0.5 to 18 V.
9	C	input	Binary channel select input, most significant address bit; logic levels per the VIH/VIL specification.
10	B	input	Binary channel select input, middle address bit; logic levels per the VIH/VIL specification.
11	A	input	Binary channel select input, least significant address bit; logic levels per the VIH/VIL specification.
12	3	passive	Analog switch channel 3 terminal, connected to COM when addressed by A/B/C with INH low.
13	0	passive	Analog switch channel 0 terminal, connected to COM when addressed by A/B/C with INH low.
14	1	passive	Analog switch channel 1 terminal, connected to COM when addressed by A/B/C with INH low.
15	2	passive	Analog switch channel 2 terminal, connected to COM when addressed by A/B/C with INH low.
16	VDD	power_in	Positive supply; recommended VDD-VSS is 3 to 15 V and absolute maximum DC supply VDD-VSS is -0.5 to 18 V.
