Product Details
Here are some key features and functions of the CD4038 counter IC:
Decade Counter: The CD4038 is a 5-stage Johnson counter, also known as a decade counter. It has 10 outputs (Q0 to Q9), which represent the binary counting sequence from 0000 to 1001 in one cycle.
Divide-by-N Function: The CD4038 can be configured to divide the input clock signal by a specific factor, N, where N is any value from 2 to 10. This makes it useful for frequency division applications.
Multiplexed Output: The outputs (Q0 to Q9) are multiplexed, meaning that only one output is active (high) at a time during the counting sequence. The multiplexed output allows the IC to reduce the number of pins required for the output connections.
Control Inputs: The CD4038 includes control inputs such as CLK (clock input), R (reset), and ENABLE. These inputs allow you to control the counting behavior and reset the counter if needed.
Binary/Decade Output: The CD4038 provides an option to select between binary counting (Q0-Q9) and decade counting (B0-B3) through the use of the BINARY/DECADE (B/D) input pin.
Ripple Blanking Output: The Q5 output can be used for ripple blanking purposes, which is helpful when cascading multiple counter stages.
Wide Operating Voltage Range: The CD4038 operates over a wide supply voltage range, typically from 3V to 18V, making it suitable for various digital logic applications.
CMOS Technology: The IC is fabricated using complementary metal-oxide-semiconductor (CMOS) technology, which provides low power consumption and good noise immunity.
Applications of the CD4038 counter IC include:
Frequency Division: The CD4038 can be used to divide the frequency of an input clock signal by a fixed factor, making it useful in frequency synthesizers and clock generation circuits.
Pulse Generation: It can generate specific pulse patterns or waveforms with controlled timing and repetition rates.
Digital Counting: The IC can be used in digital counters for counting events, pulses, or other digital signals.
Sequencing and Timing: It can play a role in various sequencing and timing applications where precise control over timing sequences is required.
