Note 1) All voltage values are specified as VSS = 0V.

Note 2) If the LSI is used on condition above the absolute maximum ratings, the LSI may be destroyed. Using

the LSI within electrical characteristics is strongly recommended for normal operation. Use beyond the

electric characteristics conditions will cause malfunction and poor reliability.

Note 3) The relation VDD > VSS ≥ VLCD must be maintained.

Note 4) Decoupling capacitor should be connected between VDD and VSS due to the stabilized operation for the

LSI.
