Product Description: 74LS49 DIP BCD to 7-Segment Decoder/Driver with Open Collector Outputs
The74LS49 is a BCD to 7-Segment Decoder/Driver IC housed in a DIP-16 package. This integrated circuit decodes a 4-bit Binary Coded Decimal (BCD) input and drives a 7-segment display to represent the corresponding decimal digits (0-9). Designed with open collector outputs, the 7449 offers the flexibility to interface with higher voltage systems (up to 30V) while driving low-current segments of the 7-segment display. The IC’s open collector outputs make it ideal for driving multiple displays or interfacing with other logic circuits, such as multiplexers or decoders in multi-digit display applications.
The 74LS49 is particularly suited for digital clocks, counters, voltage meters, and other applications that require BCD-to-decimal conversion with direct display drive capabilities.
Features:
- BCD to 7-Segment Decoding: Converts a 4-bit BCD input into a 7-segment display output, ideal for representing decimal numbers in a clear, easy-to-read format.
- Open Collector Outputs: Each output is open collector, allowing external pull-up resistors and compatibility with higher voltage levels (up to 30V), making it suitable for interfacing with more complex systems.
- Drive Capability: Directly drives 7-segment displays, including LED or LCD displays, with active low outputs for each segment.
- TTL Compatible: Fully compatible with Transistor-Transistor Logic (TTL) circuits, allowing easy integration into existing TTL-based systems and logic devices.
- Standard DIP-16 Package: Available in the widely used DIP-16 form factor for easy handling, mounting, and integration into circuit boards and prototypes.
- Low Power Consumption: Optimized for energy-efficient operation, making it ideal for portable and battery-operated devices.
- Wide Voltage Range: Operates within a 4.75V to 5.25V supply voltage range, ensuring compatibility with a broad range of power systems.
- High-Speed Operation: Ensures fast response times, making it suitable for real-time systems such as clocks, timers, and counters.
- Durable and Reliable: Built with high-quality materials for dependable long-term operation in various commercial and industrial applications.
Applications:
- Digital Clocks and Timers: The 74LS49 is perfect for driving the 7-segment displays in digital clocks, timers, and countdown systems, where BCD to decimal conversion is required.
- Counters and Meters: Used in event counters, frequency meters, and other applications that display numerical data on a 7-segment display.
- Embedded Systems: Ideal for embedded designs that need to convert BCD data into readable numeric output on 7-segment displays for user interfaces.
- Industrial Equipment: Commonly found in industrial control systems, process monitors, and equipment where numerical data is displayed for monitoring or diagnostics.
- Consumer Electronics: Can be used in consumer electronic devices such as calculators, digital thermometers, and other display-based products.
- Communication Equipment: Used in telecommunications systems to convert BCD input into readable decimal outputs, displayed on digital readouts.
Package Included:
- 1 x 74LS49 BCD to 7-Segment Decoder/Driver IC
