(*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)Pin 1,4,5,6,9,11,12,13,19,26,31,32,33,34,35,37,42,43,50,51 are weak against static electoricity and surge impulse.
