PRECAUTIONS
Logic system power supply (VLS), internal logic
system power supply (VSS, VCC; VCC > VSS)
and low-level LCD drive power supply (VEE) /
logic input / high-level LCD drive power supply
(VDD)
Precautions when connecting or disconnecting
the power supply
This IC has a high-voltage LCD driver, so it may be
permanently damaged by a high current which may
flow if voltage is supplied to the LCD drive power
supply while the logic system power supply is
floating. Therefore, when connecting the power
supply, observe the following sequence.
When disconnecting the power supply, follow the
reverse sequence.
Since the logic state of the internal circuit is
unstable immediately after the logic system power
is supplied, input CKV and SPV while initializing the
internal circuit (minimum input clock number is 240
CKV).
MODE1 and MODE2 should be set to "L" during
the initializing period for setting the LCD drive
output to VEE level.
Logic system power supply (VLS) or internal
logic system power supply (VSS, VCC; VCC >
VSS) / logic input / LCD drive power supply
(VEE, VDD)
It is possible to set voltage VEE to the same as
VSS. When connecting the power supply when VEE
= VSS, observe the following sequence and the
recommended sequence figure shown below.

Maximum ratings
When connecting or disconnecting the power, this
IC must be used within the range of the absolute
maximum ratings.
Input pin setting
Input pins other than CKV and SPV must be set to
"H" or "L" level.
