詳細說明
General Description This device contains two independent positive-edge-triggered D flip-flops with complementary outputs. The information on the D input is accepted by the flip-flops on the positive going edge of the clock pulse. The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock. The data on the D input may be changed while the clock is LOW or HIGH without affecting the outputs as long as setup and hold times are not violated. A low logic level on the preset or clear inputs will set or reset the outputs regardless of the logic levels of the other inputs.

常見問題解答
What is DM74S74N?
The DM74S74N is a dual positive-edge-triggered D-type flip-flop integrated circuit (IC) designed by National Semiconductor. It is commonly used in digital electronics and microcontroller applications for data storage, synchronization, and control signal processing.
How Does DM74S74N Work?
The DM74S74N operates as a dual D-type flip-flop, capturing input data on the rising edge of the clock signal. It features two independent flip-flops within a single package, each with a data input (D), a clock input (CLK), a clear input (CLR), and complementary outputs (Q, /Q). The flip-flop latches the input data and reflects it at the outputs based on the clock signal, providing synchronized output signals.
How Many Pins does DM74S74N have and What are the Functions of the Pinout Configuration?
The DM74S74N is housed in a 14-pin DIP (Dual Inline Package) package. The pinout configuration includes:
- 1Q, 1/Q: Output and complementary output for flip-flop 1.
- 1D: Data input for flip-flop 1.
- 1CLR: Clear input for flip-flop 1.
- 1CLK: Clock input for flip-flop 1.
- GND: Ground pin.
- 2Q, 2/Q: Output and complementary output for flip-flop 2.
- 2D: Data input for flip-flop 2.
- 2CLR: Clear input for flip-flop 2.
- 2CLK: Clock input for flip-flop 2.
- VCC: Power supply pin.
What are the Pros and Cons of DM74S74N?
Pros:
- Double Flip-Flop: Contains two flip-flops in a single package, saving board space and simplifying designs.
- Positive Edge-Triggered: Provides synchronized output signals based on the rising edge of the clock signal.
- Wide Operating Voltage Range: Supports a wide range of power supply voltages for versatile use.
- Simple Functionality: Straightforward D-type flip-flop operation for basic data storage and control applications.
Cons:
- Limited Features: Basic flip-flop functionality without advanced features like asynchronous clear or preset.
- Obsolete: As a National Semiconductor product, availability and support may be limited due to its obsolete status.
Are There Any Equivalents/Alternatives to DM74S74N for Recommendation?
As the DM74S74N is an obsolete part, newer equivalents and alternatives for dual D-type flip-flops include the 74HC74 from NXP Semiconductors, the CD74AC74 from Texas Instruments, and the MC74VHC74 from ON Semiconductor.
