James ★★★★★ Oct 22, 2026

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 ★★★★★ Oct 21, 2026

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 ★★★★★ Oct 20, 2026

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.
