Design a Custom BoardAbout This Component
Octal D-type flip-flop latch with common clock and clear inputs. Captures and holds 8 bits of data on the rising clock edge, with active-low asynchronous reset. HCT logic compatible with TTL voltage levels. Commonly used for parallel data storage and bus interfacing in digital systems.
Package: SSOP-20 (5.3×7.2mm) · 20 pins
Why does this need a breakout?
The 0.65mm pitch and narrow 5.3mm width make hand soldering this SSOP-20 extremely difficult without specialized equipment. A breakout board routes pins to standard 2.54mm headers, enabling breadboard prototyping and eliminating microscopic soldering. Ideal for evaluating microcontrollers and peripheral ICs during development.
