LC88FC2D0B
■ Power Pin Treatment Conditions 1 (VDD1, VSS1)
Connect capacitors that meet the following conditions between the V_DD1 and V_SS1 pins:
- Connect among the V_DD1 and V_SS1 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 0.1 F or larger.
- The V_DD1 and V_SS1 traces must be thicker than the other traces.

■ Power Pin Treatment Conditions 2 (VDD(2, 3, 4), VSS(2, 3, 4))
Connect capacitors that meet the following condition between the VDD(2, 3, 4) and VSS(2, 3, 4) pins:
- Connect among the VDD(2, 3, 4) and VSS(2, 3, 4) 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 0.1 F or larger.
- The VDD(2, 3, 4) and VSS(2, 3, 4) traces must be thicker than the other traces.
