CD4051BDRG

HANSCHIP semiconductor · Analog Switches, Multiplexers · SOP-16

CD4051BDRG from HANSCHIP semiconductor, in a SOP-16. 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	Y4	bidirectional	Input/output channel Y4; connects to common port Z when E is low and address inputs select channel 4.
2	Y6	bidirectional	Input/output channel Y6; connects to common port Z when E is low and address inputs select channel 6.
3	Z	bidirectional	Common input/output port; selectively connects to one of Y0-Y7 based on address inputs A0-A2 when enable E is low.
4	Y7	bidirectional	Input/output channel Y7; connects to common port Z when E is low and address inputs select channel 7.
5	Y5	bidirectional	Input/output channel Y5; connects to common port Z when E is low and address inputs select channel 5.
6	E	input	Enable input (active low); when low, address inputs A0-A2 select the active channel; when high, all switches are off-state.
7	VEE	power_in	Negative power supply voltage reference; range -18V to +0.5V relative to VSS.
8	VSS	power_in	Ground reference for digital control inputs and analog signal common return.
9	A2	input	Address select input (most significant bit); together with A1 and A0 selects which Y channel connects to Z when E is low.
10	A1	input	Address select input (middle bit); together with A2 and A0 selects which Y channel connects to Z when E is low.
11	A0	input	Address select input (least significant bit); together with A2 and A1 selects which Y channel connects to Z when E is low.
12	Y3	bidirectional	Input/output channel Y3; connects to common port Z when E is low and address inputs select channel 3.
13	Y0	bidirectional	Input/output channel Y0; connects to common port Z when E is low and address inputs select channel 0.
14	Y1	bidirectional	Input/output channel Y1; connects to common port Z when E is low and address inputs select channel 1.
15	Y2	bidirectional	Input/output channel Y2; connects to common port Z when E is low and address inputs select channel 2.
16	VDD	power_in	Positive power supply voltage; range 3V to 18V relative to VSS.
