Product Specification

Functionality D FLIP FLOP Number of Pins 14 Ic Pin 14 This IC features two independent positive-edge-triggered D flip-flops, each with complementary outputs. The flip-flops capture the value on the D input at the moment of a positive clock edge—meaning the output updates precisely when the clock transitions from LOW to HIGH. Importantly, the triggering action depends on reaching a certain voltage threshold, not on the speed of the clock’s rising edge.

While the clock is either LOW or HIGH, you can safely change the data at the D input without affecting the output, provided the setup and hold time requirements are met. Additionally, the preset and clear inputs are asynchronous: applying a LOW signal to either will immediately set or reset the outputs, regardless of other input conditions. This makes the 7474 IC a reliable choice for applications requiring precise data storage and control.

FAQs

Technical Details & Datasheet

Looking for more technical information? The IC 7474 is a dual D-type flip-flop, a staple in digital circuit design. For those who want to dive deeper into its specifications or reference official data, the manufacturer’s datasheet is your best friend. You can typically find the detailed datasheet for the 7474 from trusted sources such as Texas Instruments or ON Semiconductor—just search for "7474 D Flip Flop datasheet" to access the official PDF. There, you'll find pin configurations, electrical characteristics, timing diagrams, and application notes to guide your next project.

How Do the Preset and Clear Inputs Work?

The 7474 dual D-type flip-flop includes preset and clear inputs that provide direct control over the output states. If you apply a low (logic 0) signal to the preset pin, the Q output will immediately set to high, no matter what’s happening on the clock or data inputs. Similarly, sending a low signal to the clear pin instantly resets the Q output to low. This means you can instantly set or reset the output, overriding normal flip-flop operation—perfect for when you need to initialize or force a state in your circuit.

When Does the 7474 D Flip-Flop Accept Data?

The 7474 dual D-type flip-flop captures the value on its D input at the moment the clock signal transitions from low to high—a positive edge. In other words, the flip-flop "remembers" the input present on D right as the clock receives a rising edge. The chip includes two separate flip-flops, each with complementary Q and Q̅ outputs, making it a popular choice for memory storage or edge-triggered logic applications.

How Positive-Edge Triggering Works on the 7474 D-type Flip-Flop

The 7474 D-type flip-flop is designed with two independent units, each responding specifically to the rising edge (or positive edge) of a clock signal. What does this mean for your circuit? When you apply a clock pulse, the flip-flop looks for that moment when the clock signal transitions from low to high. Only at this precise moment does it capture and transfer the logic level present at its D (data) input over to its output. Here are a few key points about its operation:

Edge Sensitivity: The flip-flop reacts strictly to the rising edge of the clock—changes at other times don’t affect the output.
Data Setup and Hold: You can change the data at the D input freely while the clock is either low or high. The only rule: make sure your data is stable just before and just after the rising edge, so the flip-flop can latch it correctly.
No Need to Worry About Clock Rise Time: The exact speed at which the clock rises isn’t critical—the flip-flop is only watching for the transition, not how quickly it gets there.

In summary, the 7474 ensures reliable data storage with every rising clock pulse, making it a staple for timing and sequencing tasks in digital circuits.

Data Integrity with Setup and Hold Times

When using the 7474 dual D-type flip-flop, you can freely change the data on the D input as long as the required setup and hold times are maintained. In this case, the outputs (Q and Q̅) will remain stable, and only update on the active clock edge. This means your logic signals are reliably transferred to the outputs, with no unexpected glitches or changes—as long as those timing requirements are met.

What are the supply and input voltage ratings for the 7474 dual D-type flip-flop?

Voltage Ratings

Maximum Supply Voltage: 7V
Maximum Input Voltage: 7V

These ratings ensure reliable operation and protect the 7474 dual D-type flip-flop from potential damage during use.

What is the operating free air temperature range for the 7474 dual D-type flip-flop?

Operating Temperature Range

Wondering about environmental specs? The 7474 dual D-type flip-flop is designed to function reliably in standard conditions, with an operating free air temperature range from 0°C up to +70°C. That means you can count on dependable performance whether you’re prototyping in the lab, working on a classroom project, or integrating it into a commercial solution.

What is the storage temperature range for the 7474 dual D-type flip-flop?

Storage Temperature Range

You can safely store the 7474 dual D-type flip-flop in environments ranging from -65°C up to 150°C. This wide temperature tolerance ensures reliable preservation whether you're stocking up for future projects or keeping spares on hand for bench work.
