Power Pin Treatment Recommendations (VDD1, VSS1)
Connect bypass capacitors that meet the following conditions between the VDD1 and VSS1 pins:
• Connect among the VDD1 and VSS1 pins and bypass capacitors C1 and C2 with the shortest possible heavy lead
wires, making sure that the impedances between the both pins and the bypass capacitors are as equal as possible
(L1=L1', L2=L2').
• Connect a large-capacity capacitor C1 and a small-capacity capacitor C2 in parallel.
The capacitance of C2 should be approximately 0.1μF.
