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.
