(*1)When using this device at above Ta=25•, the power dissipation decreases by 15.9mV per 1•rise.

(*2) This IC 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 20 cm, or if cannot, placing shield metal

over the IC, is recommended in an application.

(*3)This IC is weak against static electoricity and surge impulse. Please take counter measure to meet, if necessary.
