概述

Description

The CD4017BM is a decade counter IC (Integrated Circuit) commonly used in digital electronics for counting applications. It operates with a binary coded decimal (BCD) format, counting from 0 to 10, and can drive up to 10 outputs sequentially. The counter increments its output on the leading edge of an input clock signal, activating one of the ten outputs (Q0-Q9) in succession while providing a carry-out pulse when it reaches the count of 10.
This IC is designed for a wide supply voltage range (3V to 15V) and features low power consumption, making it ideal for battery-operated devices. Its applications include LED chasers, digital clocks, frequency dividers, and various counting applications in microcontroller projects. The CD4017BM is often paired with other components like 555 timers for generating clock signals. Its versatility and ease of use make it a popular choice for hobbyists and professionals in electronics.

Features

The CD4017BM is a decade counter and decoder integrated circuit (IC) that counts from 0 to 10. Key features include:
1. 10 Decoded Outputs: Provides ten outputs (Q0 to Q9) that go high sequentially with each clock pulse.
2. Asynchronous Reset: Features a reset pin for immediate resetting to zero.
3. Carry Out: Outputs a carry signal when it reaches the count of 10, allowing cascading with other CD4017 ICs.
4. Low Power Consumption: Operates at low power, making it suitable for battery-operated applications.
5. Wide Voltage Range: Supports a supply voltage range from 3V to 15V, compatible with various projects.
6. TTL Compatible: Compatible with TTL logic levels, facilitating integration with other digital circuits.
7. Temperature Range: Operates effectively within a temperature range of -55°C to +125°C.
The CD4017BM is commonly used in LED chasers, digital clocks, and other timing applications due to its simplicity and reliability.

Package

The CD4017BM is typically available in a 16-pin Dual In-Line Package (DIP) format, as well as other package types like Surface Mount Device (SMD) options. The most common DIP configuration is the 16-DIP package.
