Power Pin Treatment Conditions 1 (VDD1, VSS1)
Connect capacitors that meet the following conditions between the VDD1 and VSS1 pins:
• Connect among the VDD1 and VSS1 pins and the capacitors C1 and C2 with the shortest possible lead wires,
of the same length (L1=L1', L2=L2') wherever possible.
• Connect a large-capacity capacitor C1 and a small-capacity capacitor C2 in parallel.
The capacitance of C2 should be approximately 0.1μF or larger.
• The VDD1 and VSS1 traces must be thicker than the other traces.

Power Pin Treatment Conditions 2 (VDD(2, 3), VSS(2, 3))
Connect capacitors that meet the following condition between the VDD (2, 3) and VSS (2, 3) pins:
• Connect among the VDD (2, 3) and VSS (2, 3) pins and the capacitor C3 with the shortest possible lead wires,
of the same length (L3=L3') wherever possible.
• The capacitance of C3 should be approximately 0.1μF or larger.
• The VDD (2, 3) and VSS (2, 3) traces must be thicker than the other traces.
