Notes:
2. DC Current Transfer Ratio (CTR
CE
) is defined as the transistor collector current (I
CE
) divided by the input LED
current (I
F
) x 100%, at a specified voltage between the collector and emitter (V
CE
).
3. The collector base Current Transfer Ratio (CTR
CB
) is defined as the transistor collector base photocurrent (I
CB
)
divided by the input LED current (I
F
) time 100%.
4. Referring to Figure 16 the T
PHL
propagation delay is measured from the 50% point of the rising edge of the data input
pulse to the 1.3 V point on the falling edge of the output pulse.
5. Referring to Figure 16 the T
PLH
propagation delay is measured from the 50% point of the falling edge of data input
pulse to the 1.3 V point on the rising edge of the output pulse.
