74HC574 八位元D型正反器 (DIP 20) (5入組)

The 20-pin DIP layout made soldering these onto my breadboard adapter a breeze, and all five chips clocked in without a glitch. Running them at 5V for a register project, the propagation delay feels snappy for the price. Solid value when you need spare 74HC574s around.

The DIP-20 footprint is exactly what I needed for my breadboard prototype, and having five in the pack means I can afford to make a wiring mistake without ordering again. Pins are clearly marked, so no squinting with a magnifier.

Finally a DIP‑20 octal flip‑flop pack that includes five units—perfect for breadboard prototyping without having to order singles. The 20‑pin layout made soldering into my 74HC test jig straightforward, and all five chips ran cleanly on the first try using a standard 5V supply.
