The MC14029BCPG is a four–bit parallel binary counter. It contains four master–slave flip–flops and additional logic gates to provide internal look–ahead capability. The device is suitable for frequency division applications and can be used to divide clock frequency by any integer from 3 to 15.

Application Fields
The MC14029BCPG is a powerful parallel four bit binary counter which has various applications in the field of digital electronics. It can be used in various counting and frequency division applications. It can also be used for digital frequency synthesis and for applications using Advanced Encryption Standard (AES) algorithms.

Working Principle
The MC14029BCPG is a four bit synchronous counter. It consists of four master-slave flip-flops and additional logic gate circuits to provide internal look-ahead capability. The pins C0, C1, C2, and C3 are the outputs of the four flip-flops, which are connected to the four internally clocked master-slave flip-flops. The inputs CE and CP are connected to an OR gate, which enables the output Q of the flip-flop to be clocked and reset. The CE input is used to enable the counter. The CP input is a clock pulse input, which determines the frequency at which the counter will count. When the CP input is low, the counter counts upward; when the CP input is high, the counter counts downward. The outputs QA and QB of the flip-flops are connected to an XOR gate and provides an output that is the inverse of the input. The output of the XOR gate is connected to the reset input of the flip-flop, resulting in the counter counting in the backward direction.

In many instances, the available counter range (from 3 to 15) may not be sufficient for a given application. The MC14029BCPG can be used in combination with a binary divider circuit. A basic binary divider circuit consists of an AND gate connected to the reset input of the MC14029, and two or more NOT gates connected to the CK and CE inputs of the MC14029, depending on the required output frequency.

The MC14029BCPG is a versatile counter that allows for simple frequency division applications. It can be used to generate a wide range of output frequencies and is suitable for applications requiring high frequencies. The device is available in 8-pin SMD and 16-pin PDIP packages.
