What are the key features of SN74AHC74N-P2?
- Dual independent positive-edge-triggered D flip-flops in a single 14-pin DIP package
- Wide 2 V to 5.5 V supply voltage range for mixed-voltage board compatibility
- Individual asynchronous active-low preset and clear inputs per flip-flop
- AHC logic family: lower power than AHCT with CMOS input thresholds
- 14-pin 0.300 inch DIP through-hole package for prototyping and breadboard use
What is SN74AHC74N-P2 used for?
The SN74AHC74N-P2 is widely used in digital logic designs requiring edge-triggered data latching, frequency-divide-by-two circuits, or simple finite state machines. Its dual independent flip-flop architecture allows two separate pipeline stages or clock domain registers to share a single IC, reducing component count. Hobbyist prototyping boards, educational lab kits, and low-volume industrial control panels benefit from its convenient 14-pin through-hole DIP form factor.

Frequently Asked Questions
What supply voltage range does the SN74AHC74N-P2 support, and how does it compare to 5 V-only logic families?
The SN74AHC74N-P2 operates from 2 V to 5.5 V, making it compatible with both 3.3 V and 5 V logic rails, unlike older CMOS families restricted to a single 5 V supply, giving designers greater flexibility in mixed-voltage systems.
How many flip-flop elements does the SN74AHC74N-P2 contain, and what asynchronous controls does each element have?
The device contains 2 independent D flip-flops, each with its own active-low asynchronous preset and clear inputs, a dedicated clock pin, and complementary Q and Q-bar outputs — all contained within a 14-pin DIP package.
When is the 14-pin DIP through-hole package preferred over surface-mount alternatives for this flip-flop?
The 0.300 inch 14-pin DIP package is preferred for breadboard prototyping, educational lab experiments, and low-volume hand-soldered boards where surface-mount packages under 5 mm footprint would require reflow oven assembly or fine-tip soldering skills.
