Architecture of CD4017 IC
The CD4017 IC is a 8-bit synchronous counter IC that contains a decade counter with an 8-bit synchronous counter, making it suitable for use in various remote control applications. The IC has 14 pins, with 8 being available for output. The architecture of the CD4017 IC includes:
* **Pin 1:** Clear Input (CI). This pin is used to activate the glitch-free clear function for the entire counter.
* **Pin 2:** Clock Input (CK). This pin is used to supply the clock input signal for the IC.
* **Pins 3-10:** Output Pins (Q0-Q7). These pins provide the output of each stage of the counter.
* **Pin 11:** Output Enable (OE). This pin is used to enable or disable the output of the IC.
* **Pin 12:** Inhibit Input (I). This pin is used to inhibit the counting function.
* **Pins 13 and 14:** No Connect (NC). These pins are not used and are connected internally.
Operational Modes of CD4017 IC
The CD4017 IC can operate in two modes: asynchronous mode and synchronous mode.
* **Asynchronous Mode:** In this mode, the clear input (CI) is connected to ground, and the clock input (CK) is connected to a stable voltage source. The counter counts up to 10 with each clock pulse and resets back to 0 with each clear pulse.
* **Synchronous Mode:** In this mode, the clear input (CI) is connected to the output pin (Q7), and the clock input (CK) is connected to a stable voltage source. The counter counts up to 10 with each clock pulse and resets back to 0 with each clock pulse.
Application of CD4017 IC in Remote Control Systems
The CD4017 IC is widely used in remote control systems, including:
* **Radio Frequency (RF) Remote Controllers:** These use the CD4017 IC to decode the RF signal received from the remote control and generate a precise pulse output to control the appliance.
* **Infrared (IR) Remote Controllers:** These use the CD4017 IC to decode the IR signal received from the remote control and generate a precise pulse output to control the appliance.
* **Wired Remote Controllers:** These use the CD4017 IC to count the number of pulses received from the remote control and generate a precise pulse output to control the appliance.
