Description

The HEF4017BT is a decade counter IC (integrated circuit) that counts from 0 to 10, providing a binary-coded decimal output. This CMOS (Complementary Metal-Oxide-Semiconductor) device operates on a wide voltage range, typically from 3V to 15V, making it versatile for various applications.
The HEF4017BT features ten output pins, each corresponding to a count from 0 (Q0) to 9 (Q9), and it can be cascaded with other counters for extended counting capabilities. It has a clock input (CP) for advancing the count with each pulse, a reset input to set the counter back to zero, and a carry output that signals when the maximum count is reached.
Common applications for the HEF4017BT include digital clocks, frequency dividers, and light chasers in LED displays. Its simplicity and ease of integration into circuits make it popular among hobbyists and professionals alike.

Features

The HEF4017BT is a decade counter IC that counts from 0 to 10. Key features include:
1. Count Outputs: It provides 10 separate output pins (Q0 to Q9) that go high sequentially with each clock pulse, indicating the current count.
2. Clock Input: It operates with a single clock input, allowing for easy interfacing with other digital components.
3. Reset Function: The counter can be reset to zero using an asynchronous reset pin, facilitating control over counting.
4. Decade Counting: It counts in a mod-10 fashion, which is ideal for applications requiring decimal counting.
5. Low Power Consumption: Designed for low power applications, making it suitable for battery-operated devices.
6. Wide Voltage Range: It operates over a voltage range of 3V to 15V, providing versatility in various electronic projects.
7. Propagation Delay: Offers a quick response time with low propagation delay, suitable for high-speed applications.
Overall, the HEF4017BT is ideal for counters, timers, and frequency division applications in digital circuits.

Package

The HEF4017BT is typically available in a 16-pin dual in-line package (DIP) configuration. It can also be found in surface mount options, such as the SOIC-16 package.
