The HEF4040BP652 is a type of IC component that belongs to the HEF4000 family of devices. It is a 12-stage binary ripple counter with a built-in oscillator, useful in dividing various clock frequencies.
One of the key features of the HEF4040BP652 is its ability to divide the frequency of an external clock signal applied to its input pin. The chip can divide the frequency by powers of 2 up to 2^12 (4096), allowing for a wide range of division options.
Another important feature is the inbuilt oscillator, which allows for frequency division even without an external clock input. The oscillator is controlled by an external resistor and capacitor connected to specific pins of the IC.
The HEF4040BP652 operates at a supply voltage ranging from 3V to 15V, making it compatible with a wide variety of systems. It consumes low power, making it suitable for battery-powered applications as well.
It also has a low voltage (logic level) control input, which can reset the counter or disable the oscillator when needed. The output stage of the IC is designed to directly drive high-capacitance loads, making it suitable for various applications.
The HEF4040BP652 IC is designed with a high noise immunity, meaning it is less susceptible to external noise interference. This allows for reliable operation even in noisy environments
