NOTE

1. The VCCO and VCCI supply voltages to the device must each be bypassed by a 0.1µF capacitor or larger. This can be either a

ceramic or solid tantalum capacitor with good high frequency characteristics. Its purpose is to stabilize the operation of the high-

gain amplifiers. Failure to provide the bypass will impair the DC and switching properties. The total lead length between capaci-

tor and optocoupler should not exceed 1.5mm. See Fig. 20.

2. Device considered a two-terminal device. Pins 1, 2 and 3 shorted together, and Pins 4, 5 and 6 shorted together.
