CD4016 pinout
The pinout of the CD4016 quad bilateral switch IC is as follows:
Pin Description:
- VDD (Pin 1): This is the positive power supply pin. Connect it to the VDD voltage level (typically +5V) of your system.
- VSS (Pin 14): This is the ground pin. Connect it to the ground (0V) of your system.
- IN1-IN4 (Pins 2-5): These are the input pins of the CD4016 Quad Bilateral Switch. Each input pin corresponds to one switch of the quad bilateral switch. Apply control signals to these pins to control the flow of signals through the switches.
- OUT1-OUT4 (Pins 13-10): These are the output pins of the CD4016. Each output pin corresponds to one switch and provides the output signal based on the input control signals.
- EN/INH (Pin 9): This is the Enable/Inhibit pin. When this pin is held high (logic 1), the bilateral switches are enabled and operate according to the input control signals. When this pin is held low (logic 0), the switches are inhibited, and the outputs are held at a high-impedance state.
It is important to note that the CD4016 is available in different package types (e.g., DIP-14, SOIC-14) and the pin numbering may vary slightly depending on the package.
