The DM54S472J is a J-K master-slave flip-flop manufactured by Rochester Electronics. This device belongs to the 54S series of Schottky TTL (Transistor-Transistor Logic) integrated circuits, known for their high-speed operation. The DM54S472J is a dual flip-flop, meaning it contains two independent J-K flip-flops within a single package.
Applications:
- Shift Registers: Used as building blocks in high-speed shift registers.
- Counters: Implemented in synchronous and asynchronous counters.
- Frequency Dividers: Employed in frequency divider circuits.
- Control Registers: Used in control circuits for temporary data storage.
- Memory Systems: Integrated into memory address decoding and data storage circuits.
Features:
- Dual J-K Flip-Flops: Contains two independent J-K flip-flops in one package.
- Master-Slave Configuration: Provides improved noise immunity and eliminates race-around problems.
- Schottky TTL Technology: Offers high-speed operation with typical propagation delays of a few nanoseconds.
- Separate Clock, Clear, and Preset Inputs: Allows for flexible control of each flip-flop.
- Positive Edge Triggered: Triggered on the positive-going transition of the clock signal.
- TTL Compatible: Directly compatible with other TTL devices.
Benefits:
- High-Speed Operation: Enables fast data processing and control functions.
- Improved Noise Immunity: Master-slave configuration reduces susceptibility to noise.
- Versatile Functionality: J-K flip-flops can be configured for a variety of applications.
- Reduced Component Count: Dual flip-flops in a single package saves board space and reduces cost.
- Easy to Interface: TTL compatibility simplifies integration with other digital components.
The DM54S472J comes in a ceramic dual in-line package (DIP) suitable for through-hole mounting. It requires a 5V power supply and typically operates over the military temperature range of -55°C to +125°C. Its high-speed characteristics and versatile functionality make it ideal for demanding digital applications.
