Design a Custom BoardAbout This Component
Dual JK-type flip-flop with clock and asynchronous preset/clear inputs. Fabricated in high-speed CMOS technology with TTL-compatible inputs. Common applications include frequency division, binary counters, and sequential logic circuits requiring edge-triggered storage elements.
Package: SOIC-16 (3.9×9.9mm) · 16 pins
Why does this need a breakout?
The 1.27mm pin pitch on this 16-pin package makes hand-soldering impractical and breadboard mounting impossible. A breakout board brings the pins to standard 2.54mm spacing, enabling quick prototyping of RS-232/RS-485 transceivers, ADCs, and line drivers without requiring surface-mount soldering skills or PCB fabrication.
