VDD1, VSS1 Terminal Condition
It is necessary to place capacitors between VDD1 and VSS1 as describe below.
• Place capacitors as close to VDD1 and VSS1 as possible.
• Place capacitors so that the length of each terminal to the each leg of the capacitor be equal (L1 = L1’, L2 = L2’).
• Place high capacitance capacitor C1 and low capacitance capacitor C2 in parallel.
• Capacitance of C2 must be more than 0.1µF.
• Use thicker pattern for VDD1 and VSS1.

VDD3, VSS3 Terminal Condition
It is necessary to place capacitors between VDD3 and VSS3 as describe below.
• Place capacitors as close to VDD3 and VSS3 as possible.
• Place capacitors so that the length of each terminal to the each leg of the capacitor be equal (L3 = L3’).
• Capacitance of C3 must be more than 0.1µF.
• Use thicker pattern for VDD3 and VDD3.
