Pin Overview
| Pin Name | Pin # | Type | Description |
|---|---|---|---|
| VDD | 14 | Power | Supply Voltage (+3 to +15V) |
| GND | 7 | Power | Ground (0V) |
| A, B, C, D, E, F | 1, 3, 5, 9, 11, 13 | Input | Inputs to the inverters |
| A, B, C, D, E, F | 2, 4, 6, 8, 10, 12 | Output | Outputs from inverters |
What is an Inverter/NOT gate?
The CD4069 is a CMOS logic chip that contains six independent inverters. It is used to invert a signal, meaning it takes an input signal and produces an output signal that is the opposite of the input.
How to Use the CD4069 in a Circuit?
To use the CD4069 in a circuit, you need a power supply voltage of 3 to 15V (some versions support up to 20V, so check the datasheet of your version). Connect the power supply to the VDD and GND pins of the chip. You can now use any of the six inverters in the chip.
