FAQs
What is DM7474N?
The DM7474N is a dual D-type positive-edge-triggered flip-flop designed by Fairchild Semiconductor. It is commonly used in digital systems for data storage, transfer, and synchronization.
How Does DM7474N Work?
The DM7474N operates as a bistable multivibrator, storing one bit of data in each flip-flop. It triggers its outputs based on the rising edge of the clock input, allowing for synchronous data processing. The dual flip-flop configuration provides two separate storage elements within a single IC package.
How Many Pins does DM7474N have and What are the Functions of the Pinout Configuration?
The DM7474N is housed in a 14-pin DIP (Dual Inline Package) package. The pinout configuration includes:
- CLK: Clock input for data triggering.
- D: Data input for each flip-flop.
- Q: Output for each flip-flop.
- Q bar: Complementary output for each flip-flop.
- PRE, CLR: Preset and clear inputs for asynchronous control.
- GND: Ground pin.
- VCC: Positive power supply pin.
What are the Pros and Cons of DM7474N?
Pros:
- High Noise Immunity: Provides good noise margin for reliable operation.
- Simple Operation: Easy to use in digital circuits for basic flip-flop functionality.
- Dual Flip-Flop: Contains two flip-flops in a single package, saving board space.
- Wide Operating Voltage Range: Supports a wide range of supply voltages for flexibility in system design.
Cons:
- Asynchronous Inputs: The preset and clear inputs may require careful consideration in synchronous designs to avoid unintended triggering.
- Power Consumption: May have higher power consumption compared to more modern flip-flop designs.
Are There Any Equivalents/Alternatives to DM7474N for Recommendation?
- The SN74LS74A from Texas Instruments is an equivalent dual D-type flip-flop.
- Alternatives to the DM7474N include the CD4013 from Texas Instruments and the MC74HC74A from ON Semiconductor.
