DM7476N

Overview

The DM7476N is a dual master-slave J-K flip-flop integrated circuit manufactured by onsemi. It operates within a supply voltage range of 4.75V to 5.25V and supports a maximum clock frequency of 15 MHz. The device features preset and clear inputs, along with complementary outputs. It is housed in a 14-pin Mini-DIP package with a standard 0.300-inch width. The component is designed for through-hole mounting and functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Dual master-slave J-K flip-flop architecture providing two independent 1-bit storage elements
• Integrated preset and clear control inputs for direct state management
• Complementary output configuration available for each flip-flop element

Applications

• Digital logic circuits requiring binary data storage
• Frequency division and counting applications
• Shift register construction in digital systems

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm that existing inventory meets long-term supply requirements or plan for redesign. Ensure compatibility with 5V logic levels and through-hole manufacturing processes. Check datasheet revisions for any specific handling or testing recommendations associated with end-of-life products.

Selection Notes

Select this component only when a dual J-K flip-flop with complementary outputs is required in a through-hole package. Consider the 15 MHz clock limit and 5V supply constraint during system design. Evaluate alternative modern logic families if RoHS compliance or surface-mount technology is necessary for the target application.
