The HEF4024BP,652 is a basic 3-stage Binary Ripple Counter with an active low Reset derived from NAND gates. This device is suitable for applications that require a frequency divider or a sequential counter in combination with digital systems. The device features a common reset terminal and is available in a wide range of packages.

The HEF4024BP,652 is manufactured in different versions by the Fairchild Semiconductor. All versions are available in the 8-pin DIP, 8-pin PDIP, 16-pin DIP, 16-pin PDIP, 20-pin DIP, 20-pin PDIP, SO-14 and ceramic flatpack packages. It features a maximum supply voltage of 5V and a total of 24 output count stages.

The HEF4024BP,652 is a 3-stage binary ripple counter with an active-low reset. It has an asynchronous reset input and an asynchronous reset output synchronous with the count stages. It can be clocked with an active low or active high input. The output logic is configurable and can be either an open-drain (CMOS) configuration or a totem-pole (TTL) configuration. The clocking rate is determined by the external timing components and the logic speed is also adjustable.

The HEF4024BP,652 comprises of two different types of logic cells. Firstly, it contains a three-stage binary ripple counter. This consists of a D flip-flop, an AND gate, an XOR gate and an OR gate. The D flip-flop and the XOR gate are used to create the count stages and the AND gate and OR gate are used to create the reset logic. The second type of logic cell is an active-low reset which consists of an AND gate followed by an XOR gate. This active-low reset is used to reset the counter to all zeros.

The HEF4024BP,652 application fields include frequency division, frequency generators, analog-to-digital converters and other digital logic applications. It is used in timing, clocking and frequency division systems. The basic logic of the HEF4024BP,652 can be employed to control various electromechanical components, such as motor speed controllers, motor driver circuits, motor control units etc. It is also suitable for high speed logic circuits, as it is capable of operating at a clock speed of up to 300MHz.

The working principle of the HEF4024BP,652 is based on the sequential logic of a 3-stage binary ripple counter. The counter counts the clock pulses generated by an external source. When the counter reaches the maximum count (24), it resets itself to 0. When the reset terminal is low, the counter is reset to 0. The output logic of the HEF4024BP,652 is configured to be either an open-drain (CMOS) configuration or a totem-pole (TTL) configuration.

In conclusion, the HEF4024BP,652 is a 3-stage binary ripple counter with an active-low reset. It is applicable for frequency division, frequency generators, analog-to-digital converters and other digital logic applications. The output logic is configurable and the clocking rate is determined by the external timing components. The maximum clock speed is up to 300MHz. Furthermore, the reset logic is an ANDgate followed by an XOR gate which is used to reset the counter to 0.
