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. |
