CD4017BE

Features of CD4017

1. 10 Decoded Outputs (Q0–Q9): Sequentially activates one output at a time with each clock pulse, ideal for creating time-delay circuits and LED chasers.
2. Clock Input: Accepts clock pulses to trigger the counting sequence.
3. Reset Pin: Allows resetting the count back to Q0, enabling flexibility in design.
4. Carry-Out Pin: Facilitates cascading multiple CD4017 ICs for extended counting sequences.
5. Wide Operating Voltage Range: Operates between 3V and 15V, compatible with a variety of digital and analog circuits.
6. Low Power Consumption: CMOS technology ensures minimal power usage, suitable for battery-powered devices.
7. High-Speed Operation: Handles clock frequencies up to 5 MHz, depending on supply voltage.
8. Noise Immunity: Designed for stable operation in noisy environments.
9. Compact Package: Available in DIP, SOIC, and other packages for easy integration.
10. Versatile Applications: Used in LED sequencing, frequency division, timers, counters, and other digital control systems.

Pinout of CD4017

1. OUT 0–OUT 9 (Pins 3, 2, 4, 7, 10, 1, 5, 6, 9, 11): The 10 outputs, activated sequentially with each clock pulse.
2. Vdd (Pin 16): Supply voltage pin (typically 3V–15V).
3. GND (Pin 8): Ground connection.
4. RESET (Pin 15): Resets the counter to its initial state (Q0 active).
5. CLOCK (Pin 14): Input for clock pulses to drive the counter.
6. ENABLE (Pin 13): Enables or disables the clock input (active low).
7. CLK/10 (Pin 12): Carry-out output that provides a pulse every 10 clock cycles, useful for cascading.
