CD4024BMG4

The CD4024BMG4 is a programmable 4-bit counter/dividers logic circuit from the Texas Instruments CMOS logic family. The device combines a 4-bit synchronous binary up/down counter and a divide-by-two circuit. This is a ‘dual mode’ device because the counter can be operated either as a 4-bit synchronous binary counter or as a divide-by-two circuit. The device is designed to count in both directions, 0 to 15 or 15 to 0. The outputs of the counter/dividers can be used to produce various types of internal or external clocks and signals, such as delayed or repeated pulse sequences.

The CD4024BMG4 logic circuit is widely used in systems like digital clocks, frequency dividers, and Frequency Shift Keying (FSK) receivers. In FSK receivers, the circuit is used to provide a divide-by-two function to reduce frequency of the received signal. The circuit is also used as a clock divider in digital clocks to reduce the frequency of the main clock.

The CD4024BMG4 circuit is a 4-bit synchronous binary up/down counter that can be used to count in both directions. It has five inputs: four for the data inputs (A, B, C, D) and one for a clock pulse input (CLK). The four data inputs are used to select the logic level (high or low) of the respective outputs. When the clock input is high, the counter advances one count. The "Carry Out" output (CO) is used to indicate the carry of the MSB (Most Significant Bit) to the next most significant bit. The “Drop Out” output (DO) is used to indicate the falling edge (transition) of the MSB. The Q output is the ‘synchronous most significant bit’ of the device.

The CD4024BMG4 circuit can be used in applications such as frequency dividers, digital clocks, and FSK receivers. In frequency dividers, the device is used to reduce the frequency of a signal. In digital clocks, the circuit is used as a clock divider to reduce the frequency of the main clock. In FSK receivers, the circuit is used to provide a divide-by-two function to reduce the frequency of the received signal.

The CD4024BMG4 logic circuit works on the simple principle of binary counting. It uses a 4-bit synchronous binary up/down counter and a divide-by-two circuit for counting in both directions, 0 to 15 or 15 to 0. The four data inputs are used to select the logic level of the respective outputs. When the clock input is high, the counter advances one count. The Q output is the ‘synchronous most significant bit’ of the device.

The circuit is an essential building block for various applications such as digital clocks, frequency dividers and FSK receivers. The device provides a reliable and economical way to reduce the frequency of a particular signal, which is needed in many applications. Thus, the CD4024BMG4 logic circuit is widely used in electronic systems.
