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.
3. For example, assuming a V
CCI
of 5.0V, and an ambient temperature of 70°C, the maximum allowable V
CCO
is 12.1V.
