(*) When using this device at above Ta = 25°C, the power dissipation decreases by 15.9 mW
per 1°C rise.
ThisIC is not proof enough against a strong E-M field by CRT which may cause function
errors and/or poor characteristics.
Keeping the distance from CRT to the IC longer than 20cm, or if cannot, placing shield
metal over the IC, is recommended in an application.
