Product Description: SN7490 DIP Decade Counter (Separate Divide-By-2 and Divide-By-5 Sections)
The SN7490 is a Decade Counter in a DIP-16 package, designed to provide divide-by-10 functionality with separate divide-by-2 and divide-by-5 sections. This versatile IC is ideal for applications where a binary counter is needed that operates in a mod-10 sequence, such as digital clocks, frequency dividers, or digital counters that count up to 10 before resetting to zero.
The 7490 consists of two main sections: a divide-by-2 section and a divide-by-5 section. These sections work together to create a decade counter that produces a counting sequence from 0 to 9. The counter is fully TTL compatible and operates with high-speed switching, making it suitable for both synchronous and asynchronous counting applications. The DIP-16 package is ideal for easy integration into breadboards, prototyping setups, and production environments.
Features:
- Decade Counter (Mod-10): The SN7490 provides divide-by-10 functionality, counting from 0 to 9 in a binary sequence before automatically resetting.
- Separate Divide-by-2 and Divide-by-5 Sections: The IC has a divide-by-2 section that counts two binary states and a divide-by-5 section that counts five binary states. Together, they form the decade counting sequence.
- TTL Compatible: Fully TTL compatible, ensuring reliable performance and integration with other TTL-based logic circuits in digital systems.
- Reset and Enable Inputs: The SN7490 includes reset and enable inputs that allow for control over the counting process, enabling or disabling the counter operation as needed.
- High-Speed Operation: Offers fast switching speeds with minimal propagation delay, enabling efficient performance in time-sensitive applications.
- Low Power Consumption: Designed to operate with low power consumption, ideal for energy-efficient designs and battery-operated systems.
- DIP-16 Package: Housed in a DIP-16 package, which is perfect for easy handling and integration into prototype circuits and PCB designs.
- Wide Voltage Range: Operates within a voltage range of 4.75V to 5.25V, offering compatibility with a wide range of power supply configurations.
Applications:
- Digital Clocks: The SN7490 is often used in digital clocks to create a time base for counting seconds, minutes, or hours, where it provides the necessary divide-by-10 function for the clock’s counting sequence.
- Frequency Division: Can be used in frequency divider circuits to divide a high-frequency signal by 10, producing a lower frequency signal for use in other parts of a system.
- Counters: Ideal for use in digital counters that count from 0 to 9 in a decade sequence, with applications in LED displays, seven-segment displays, or digital systems requiring mod-10 counting.
- Timer Circuits: Can be integrated into timer circuits that require a count-up or count-down feature in a mod-10 sequence for timing and event counting purposes.
- Pulse Generation: The 7490 is used in pulse generation circuits where it divides an input signal or clock pulse to create a desired output pulse frequency.
- Embedded Systems: In embedded system designs, the 7490 is used for counting, timing, or generating specific timing sequences needed in microcontroller-based projects.
- Frequency Synthesizers: Used in frequency synthesizer circuits, where the IC helps generate a specific frequency by dividing a reference frequency by 10.
