Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any
parameter. That is, the absolute maximum ratings are rated values at which the product is on the
verge of suffering physical damage, and therefore the product must be used under conditions that
ensure that the absolute maximum ratings are not exceeded.

Notes 1.
It is essential that V
DD1
≤
V
DD2
.
2.
These conditions are recommended when the LCD is driven by an external power supply.
3.
This condition is recommended when the LCD is driven by the internal power supply circuit.
Cautions 1. Make sure that the relationship of V

< V
LC4
< V
LC3
< V
LC2
<V
LC1
< V
LCD
≤
V
OUT
is satisfied when the
LCD is driven by an external power supply.
2. Make sure that the condition described in 8. POWER SEQUENCE are satisfied when turning
power ON or OFF.
3. Keep the voltage at the V
R
and V
RS
pins to between 1.0 V and V
DD1
when an external resistor is
used (when the internal resistor is not used to adjust V
LCD
).
