Notes
1.
Current Transfer Ratio is defined as a ratio of output collector current, IO, to the forward LED input current, IF, times 100%.
2.
The 1.9 k
Ω load represents 1 TTL unit load of 1.6 mA and 5.6 kΩ pull-up resistor.
3.
The 4.1 k
Ω load represents 1 LSTTL unit load of 0.36 mA and 6.1kΩ pull-up resistor.
4.
Common mode transient immunity in logic high level is the maximum tolerable (positive) dVcm/dt on the leading edge of the
common mode pulse signal VCM, to assure that the output will remain in a logic high state (i.e., VO>2.0 V). Common mode
transient immunity in logic low level is the maximum tolerable (negative) dVcm/dt on the trailing edge of the common mode
pulse signal, VCM, to assure that the output will remain in a logic low state (i.e., VO<0.8 V).
5. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are shorted
together.
