Abstract

The HD3SS212 requires +3.3-V digital power sources. VDD 3.3 supply must have 0.1-µF bypass capacitors to VSS (ground) in order for proper operation. The recommendation is one capacitor for each power terminal. Place the capacitor as close as possible to the terminal on the device and keep trace length to a minimum. Smaller value capacitors like 0.01-µF are also recommended on the digital supply terminals.
