PRECAUTIONS
Precautions when connecting or disconnecting
the power supply
This IC has some power supply pins, 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.
VCC / logic input / VLS, VH0-VH64, VL0-VL64
When disconnecting the power supply, follow the
reverse sequence.
Reference voltage input
The relation of the reference voltage input is shown
here.
VLS > VH0 ≥ VH8 ≥ π ≥ VH56 ≥ VH64 ≥ 0.5VLS ≥
VL64 ≥ VL56 ≥ π ≥ VL8 ≥ VL0 > GND
Maximum ratings
When connecting or disconnecting the power
supply, this IC must be used within the range of the
absolute maximum ratings.
Target output load
This IC is designed for a 150 pF output load
capacity. When using this IC for other than 150 pF
panels, confirm the device is having no problem
before using it.
