Design a Custom BoardAbout This Component
Octal D-type flip-flop with common clock and asynchronous clear input. Each flip-flop independently captures and stores data on clock rising edge. HCT technology provides TTL-compatible thresholds with CMOS power efficiency. Commonly used for parallel data latching, bus interfaces, and sequential logic applications requiring 8-bit storage.
Package: SOIC-20W (7.5mm wide) · 20 pins
Why does this need a breakout?
The 1.27mm pin pitch makes hand-soldering this 20-pin SOIC challenging and error-prone. A breakout board brings all pins to standard 0.1" spacing, enabling reliable breadboard prototyping and simplifying development of USB-to-UART interfaces without requiring reflow soldering or specialized equipment.
