概述

Description

The 74HC4024D is a high-speed CMOS binary ripple counter that counts in binary from 0 to 15 (4 bits). It operates on a supply voltage range of 2V to 6V and is designed for low power consumption and fast switching speeds, typically found in digital circuits. The device features asynchronous reset and enable inputs, allowing for flexible control of the counting process.
The counter consists of flip-flops that toggle their states on the rising edge of the clock signal. It can be used in various applications such as frequency division, event counting, and digital clocks. The 74HC series is known for its compatibility with TTL logic levels, making it suitable for interfacing with other digital devices.
Package options include DIP and SOIC, making it versatile for different PCB layouts. Overall, the 74HC4024D is an essential component in digital electronics for counting and timing applications.

Features

The 74HC4024D is a high-speed CMOS dual 7-stage binary ripple counter. Key features include:
1. Dual Counters: It contains two independent 7-stage binary counters.
2. Count Range: Each counter counts from 0 to 127 (2^7 - 1).
3. High-Speed Operation: Operates at high frequencies due to CMOS technology, with a typical propagation delay of 14 ns at 5V.
4. Wide Supply Voltage: It operates over a supply voltage range of 2V to 6V.
5. Low Power Consumption: Consumes low power, making it suitable for battery-powered applications.
6. Asynchronous Reset: Each counter features an asynchronous reset input for quick resetting to zero.
7. Parallel Load Capability: It allows loading of preset values for flexible counting applications.
8. Improved Noise Margin: High noise immunity due to CMOS design.
9. Enhanced Reliability: Designed for reliability in various environments.
This makes the 74HC4024D suitable for applications in frequency division, event counting, and digital logic systems.

Package

The 74HC4024D is commonly available in a dual in-line package (DIP) format, specifically a 14-pin DIP. It may also be found in other package types like SOIC (Small Outline Integrated Circuit) or TSSOP (Thin Shrink Small Outline Package) depending on the manufacturer.

Pinout

The 74HC4024D is a dual 7-stage ripple carry binary counter. It has a total of 14 pins. The pin functions are as follows:
1. GND (Pin 11): Ground connection.
2. VCC (Pin 14): Power supply (typically +2V to +6V).
3. RESET (Pin 1, 2): Asynchronous reset inputs for both counters; active LOW.
4. CLOCK (Pin 3, 4): Clock inputs for both counters; triggers on the rising edge.
5. Q0 to Q6 (Pins 5, 6, 7, 9, 10, 12, 13): Outputs of the counter stages (Q0 through Q6).
6. TERMINAL COUNT (Pin 8): Output that indicates when the counter reaches its maximum count.
The device counts in binary and can be used in various applications requiring counting and frequency division functions.
