CD4051BPWRG

HANSCHIP semiconductor · Analog Switches, Multiplexers · TSSOP-16

CD4051BPWRG from HANSCHIP semiconductor, in a TSSOP-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 Y4 bidirectional Independent analog input/output channel 4 that connects to common Z when selected by A0-A2 with E low; analog signals must stay between VEE and VDD and switch current is limited to ±10 mA.
2 Y6 bidirectional Independent analog input/output channel 6 that connects to common Z when selected by A0-A2 with E low; analog signals must stay between VEE and VDD and switch current is limited to ±10 mA.
3 Z bidirectional Common analog input/output that connects to whichever Y channel is selected; voltage must not exceed VDD or fall below VEE and switch current is limited to ±10 mA.
4 Y7 bidirectional Independent analog input/output channel 7 that connects to common Z when selected by A0-A2 with E low; analog signals must stay between VEE and VDD and switch current is limited to ±10 mA.
5 Y5 bidirectional Independent analog input/output channel 5 that connects to common Z when selected by A0-A2 with E low; analog signals must stay between VEE and VDD and switch current is limited to ±10 mA.
6 E input Active-low enable input: when low the channel selected by A0-A2 is switched on, and when high all switches are off (high impedance); input range is 0 to VDD.
7 VEE power_in Negative supply for the analog switches; absolute maximum is -18 V to +0.5 V referenced to VSS, recommended range -6.0 V to 0 V, and it must be tied to VSS (ground) for digital multiplexing use.
8 VSS power_in Ground and reference for the digital control inputs A0-A2 and E; 0 V is the reference used for the electrical characteristics.
9 A2 input Channel-select address input (bit 2) that, with A0 and A1, selects which Y channel connects to Z while E is low; input range is 0 to VDD.
10 A1 input Channel-select address input (bit 1) that, with A0 and A2, selects which Y channel connects to Z while E is low; input range is 0 to VDD.
11 A0 input Channel-select address input (bit 0) that, with A1 and A2, selects which Y channel connects to Z while E is low; input range is 0 to VDD.
12 Y3 bidirectional Independent analog input/output channel 3 that connects to common Z when selected by A0-A2 with E low; analog signals must stay between VEE and VDD and switch current is limited to ±10 mA.
13 Y0 bidirectional Independent analog input/output channel 0 that connects to common Z when selected by A0-A2 with E low; analog signals must stay between VEE and VDD and switch current is limited to ±10 mA.
14 Y1 bidirectional Independent analog input/output channel 1 that connects to common Z when selected by A0-A2 with E low; analog signals must stay between VEE and VDD and switch current is limited to ±10 mA.
15 Y2 bidirectional Independent analog input/output channel 2 that connects to common Z when selected by A0-A2 with E low; analog signals must stay between VEE and VDD and switch current is limited to ±10 mA.
16 VDD power_in Positive supply for the digital inputs and analog switches; absolute maximum is -0.5 V to +18 V referenced to VSS, with a recommended VDD of 3.0 V to 18 V and VDD−VEE of 5 V to 15 V.
