CD4017BE

The CD4017BE is a decade counter integrated circuit (IC) produced by HGSEMI, designed for counting applications in digital electronics. It is part of the CD4000 series of CMOS (Complementary Metal-Oxide-Semiconductor) logic ICs, which are known for their low power consumption and high noise immunity.

Key Features:

1. Decade Counter: The CD4017BE counts from 0 to 10 (0 to 9 in binary) and has ten output pins (Q0 to Q9) that go high sequentially with each clock pulse. After reaching Q9, the next clock pulse resets the counter back to Q0.

2. Power Supply: The IC operates over a wide voltage range, typically from 3V to 15V, making it versatile for various applications. It can function with both positive and negative power supplies.

3. Clock Input: The counter is triggered by a rising edge on the clock input (pin 14). This means that the counter increments its count on the transition from low to high voltage.

4. Reset Functionality: The CD4017BE includes a reset pin (pin 15) that allows the user to reset the counter to zero at any time, regardless of the current count.

5. Enable Functionality: The counter can be enabled or disabled using the enable pin (pin 11). When disabled, the counter will not increment, allowing for controlled counting.

6. Output Configuration: Each output pin (Q0 to Q9) can drive loads directly, with a maximum output current of around 10 mA per pin. This makes it suitable for driving LEDs or other low-power devices directly.

7. Temperature Range: The IC is designed to operate within a standard temperature range, typically from -40°C to +85°C, ensuring reliability in various environmental conditions.

8. Package Type: The CD4017BE is commonly available in a 16-pin dual in-line package (DIP) format, making it easy to integrate into breadboards and other prototyping setups.

Applications:

The CD4017BE is widely used in various applications, including:

• LED Chasers: Creating light chaser circuits where LEDs light up in sequence.
• Frequency Division: Dividing clock signals for timing applications.
• Event Counters: Counting events in applications such as timers or counters in digital devices.
• Tally Counters: Used in devices that require counting of items or occurrences.

Conclusion:

The CD4017BE from HGSEMI is a versatile and reliable decade counter IC that is easy to use and integrate into various electronic projects. Its combination of features, including a wide operating voltage range, reset and enable functionalities, and direct output capabilities, makes it a popular choice for hobbyists and professionals alike in the field of digital electronics.
