Description

The HEF4040BT is a binary ripple counter IC (integrated circuit) primarily used in digital electronics for counting applications. It features a 12-stage binary counter, capable of counting from 0 to 4095 (2^12 - 1). The IC operates on a wide voltage range, typically between 3V to 15V, making it versatile for various applications.
The HEF4040BT utilizes a clock input to increment the count on each rising edge and provides a binary output for each stage, allowing for easy interfacing with other digital components. It includes reset capabilities to set the count back to zero. The chip's design ensures low power consumption, making it suitable for battery-operated devices.
Applications include frequency division, time delay generation, and event counting in embedded systems and counters for digital clocks. Its reliability and simplicity make it a popular choice among engineers and hobbyists for building counter circuits and various timing applications.

Features

The HEF4040BT is a binary ripple counter IC designed for counting purposes in digital circuits. Key features include:
1. Counter Capacity: It can count up to 12 bits (from 0 to 4095).
2. Asynchronous Reset: The counter can be reset without waiting for a clock pulse, enhancing its versatility.
3. Clock Input: It operates on a standard clock input, enabling counting operations based on external signals.
4. Output Format: Outputs are provided in binary form, with individual output pins representing each bit.
5. High Noise Immunity: The design incorporates high noise immunity, ensuring reliable operation in various environments.
6. Wide Supply Voltage Range: It typically operates between 3V to 15V, allowing compatibility with a variety of circuits.
7. Low Power Consumption: The IC is designed for low power usage, making it suitable for battery-operated devices.
The HEF4040BT is widely utilized in applications like frequency dividers, timers, and digital counting systems.

Package

The HEF4040BT is typically packaged in a dual in-line package (DIP) format, specifically a 14-pin DIP. This package type allows for easy insertion into breadboards and PCB sockets, facilitating prototyping and circuit integration.

Pinout

The HEF4040BT is a 12-stage binary ripple counter, featuring a total of 14 pins. Its primary function is to count in binary and provide a digital output representing the count value.
Pin Configuration:
1. VDD (Power Supply)
2. Ground (GND)
3. Reset (Active Low)
4. Clock Input (CLK)
5. Q1 to Q12 (Binary Output Pins)
6. Carry Out (CO)
The outputs Q1 to Q12 represent the binary count from 0 to 4095, with each output corresponding to a specific bit in the binary number. The counter increments on the rising edge of the clock signal. The reset pin allows the counter to be reset to zero asynchronously. The carry-out pin indicates when the counter has reached its maximum count and can be used to cascade multiple counters.
This IC is commonly used in digital applications for counting events, time delays, and frequency division.
