Maximum ratings

When connecting or disconnecting the power

VCC / logic input / VLS, V0-V10

supply, this IC must be used within the range of the

absolute maximum ratings.

When disconnecting the power supply, follow the

reverse sequence.

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
