NOTE
VLCD1 Terminal
Note 1 : If the LSI are 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 mal function and poor reliability.
Note 2 : Decoupling capacitor should be connected between VDD and VSS , VLCD1-VSSdue to the stabilized
operation for the Voltage converter.
Note 3 : All voltage values are specified as VSS = 0V
The relation : VLCD1≥ VLCD2 > VDD> VSS , VSS=0V must be maintained.
