Michael G. ★★★★★

My latest breadboard project needed decoders and these worked perfectly right out of the package. The 3-to-8 decoding is crisp and glitch-free, and having five chips for the price is a nice bonus.

Natalie ★★★★★

Used these to build a simple addressable indicator matrix for a home project, and each chip fired up without any noise on the first try. The DIP-16 packages are a solid, easy-to-solder form factor, and having five in the pack means I have spares for the next build.

Jason H. ★★★★★

Needed to decode three address lines for an 8-output multiplexer in a breadboard project, and these DIP chips worked flawlessly straight out of the anti-static tube. The 5-pack is handy for prototyping without worrying about damaging one.
