Customer Reviews (4.6 / 5 · 5 reviews)

James ★★★★★

It was a breeze integrating this into my circuit because each of the eight outputs activates cleanly without any cross-talk. The three enable pins made it simple to cascade multiple chips for a larger addressable LED array.

Olivia ★★★★★

The three enable inputs gave me exactly the flexibility I needed to cascade two of these for a 16-channel setup, and the outputs switch cleanly without any glitching. Soldered up in minutes and decoded flawlessly on the first try.

Joseph ★★★★★

Working on a project where each output had to be mutually exclusive, this chip made the address decoding dead simple. The three enable inputs gave me exactly the control I needed for the logic.
