CD4517BEG4

The CD4517BEG4 is a dual 4-bit binary counter integrated circuit (IC) manufactured by Texas Instruments. It is part of the CD4000 series of CMOS (Complementary Metal-Oxide-Semiconductor) logic devices, which are known for their low power consumption and high noise immunity.

Key Features:

1. Dual 4-Bit Counter: The CD4517 contains two independent 4-bit binary counters, allowing it to count from 0 to 15 (in binary) for each counter. This makes it suitable for applications requiring counting or frequency division.

2. Asynchronous Reset: Each counter can be reset asynchronously, meaning that it can be set back to zero regardless of the clock signal. This feature is useful for initializing the counter to a known state.

3. Count Enable: The counters can be enabled or disabled through a count enable input, allowing for controlled counting operations. This feature is particularly useful in applications where counting needs to be paused or resumed.

4. Clock Input: The CD4517 has a clock input that triggers the counting operation. The counters increment their value on the rising edge of the clock signal.

5. Output: The outputs of the counters are available in binary form, with four output pins for each counter. These outputs can be connected to other digital circuits for further processing or display.

6. Power Supply: The IC operates over a wide voltage range, typically from 3V to 15V, making it versatile for various applications. It has low power consumption, which is advantageous for battery-operated devices.

7. Package Type: The CD4517BEG4 is available in a 16-pin dual in-line package (DIP) configuration, which is easy to handle and solder onto PCBs. The "BEG4" designation indicates that it is a specific variant with certain characteristics, such as temperature range and packaging.

8. Temperature Range: The device is designed to operate within a specified temperature range, making it suitable for both commercial and industrial applications.

Applications:

The CD4517BEG4 is commonly used in digital applications such as:

• Frequency counters
• Digital clocks
• Event counters
• Timer circuits
• Frequency division in communication systems

Conclusion:

The CD4517BEG4 from Texas Instruments is a versatile and reliable dual 4-bit binary counter that is ideal for a variety of digital counting applications. Its features, such as asynchronous reset, count enable, and low power consumption, make it a popular choice among engineers and hobbyists alike.
