Design a Custom BoardAbout This Component
Octal edge-triggered D-type flip-flop with 3-state outputs designed for bus driving applications. Operates at 4.5V to 5.5V with typical propagation delay of 22ns and ±6mA output drive. Suitable for buffer registers, I/O ports, bidirectional bus drivers, and working registers with TTL-compatible inputs.
Package: TSSOP-20 (4.4×6.5mm) · 20 pins
Why does this need a breakout?
Hand-soldering 0.65mm pitch leads is tedious and error-prone; a breakout board with standard 0.1" headers lets you prototype I/O expanders and logic gates on breadboards without a reflow oven. The compact SSOP package also becomes DIP-friendly, eliminating jumper spaghetti and reducing assembly mistakes during development cycles.
