Design a Custom BoardAbout This Component
Octal edge-triggered D-type flip-flop with 3-state outputs designed for bus driving applications. Features TTL-compatible inputs, 4.5V-5.5V operating range, 22ns propagation delay, and ±6mA output drive. Suitable for buffer registers, I/O ports, and bidirectional bus drivers.
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.
