Notes
Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluation. Typical values are for information only and are not part of the testing requirements. All typical values are measured at T
amb
= 25 °C.
(1)
A 0.1 μF bypass capacitor connected between pins 4 and 6 is recommended.
Notes
(1)
Current transfer ratio in percent equals the ratio of output collector current (I
O
) to the forward LED input current (I
F
) times 100.
(2)
A 0.1 μF bypass capacitor connected between pins 4 and 6 is recommended. All typical values are measured at T
amb
= 25 °C.
Note
(1)
The 1.9 k
Ω
load represents 1 TTL unit load of 1.6 mA and the 5.6 k
Ω
pull-up resistor. All typical values are measured at T
amb
= 25 °C.
