The CD4069UBE comes in a 14-pin Dual In-line Package (DIP) format. The table below shows the detailed pinout and their functions:
Pin Number Pin Function Pin 1 Input 1 (A1): Input pin for the first inverter. Pin 2 Output 1 (Y1): Output of the first inverter. Pin 3 Input 2 (A2): Input pin for the second inverter. Pin 4 Output 2 (Y2): Output of the second inverter. Pin 5 Input 3 (A3): Input pin for the third inverter. Pin 6 Output 3 (Y3): Output of the third inverter. Pin 7 Ground (GND): Ground connection for the IC. Pin 8 Input 4 (A4): Input pin for the fourth inverter. Pin 9 Output 4 (Y4): Output of the fourth inverter. Pin 10 Input 5 (A5): Input pin for the fifth inverter. Pin 11 Output 5 (Y5): Output of the fifth inverter. Pin 12 Input 6 (A6): Input pin for the sixth inverter. Pin 13 Output 6 (Y6): Output of the sixth inverter. Pin 14 Vcc (Supply Voltage): Power supply connection (typically +5V to +15V).Pin Function Detailed Description
Inputs (A1, A2, A3, A4, A5, A6): These are the input pins for the six inverters. The logic level on these pins determines the output at the corresponding output pins (Y1, Y2, Y3, Y4, Y5, Y6).
Outputs (Y1, Y2, Y3, Y4, Y5, Y6): These are the output pins corresponding to each input. The output will be the logical inverse (NOT) of the input. For example, if A1 is HIGH (1), then Y1 will be LOW (0), and vice versa.
Vcc (Pin 14): This is the power supply pin. A typical supply voltage for this IC is between +5V to +15V.
Ground (Pin 7): This pin connects the IC to the system ground.
Basic Circuit Principle
The basic principle of the CD4069UBE is that each of its six logic gates (inverters) takes a single binary input and outputs the inverse of that input. For instance:
If the input is high (logic 1), the output will be low (logic 0). If the input is low (logic 0), the output will be high (logic 1).This inversion is the basic operation of the CD4069UBE, and it can be used for various logic functions where an inverter is needed in a circuit.
