HCPL0XXX — High Speed Transistor Optocouplers
Notes
1 Current Transfer Ratio is designed as a ratio of output collector current, I
O
, to the forward LED input current, I
F
, times
100%.
2. The 4.1 kΩ load represents 1 LSTTL unit load of 0.36 mA and 6.1kΩ pull-up resistor.
3. The 1.9 kΩ load represents 1 TTL unit load of 1.6 mA and 5.6 kΩ pull-up resistor.
4. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV
cm
/dt on the leading edge
of the common mode pulse signal V
CM
, to assure that the output will remain in a logic high state (i.e., V
O
>2.0 V).
Common mode transient immunity in logic low level is the maximum tolerable (negative) dV
cm
/dt on the trailing edge
of the common mode pulse signal, V
CM
, to assure that the output will remain in a logic low state (i.e., V
O
<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.
6. 2500 VAC RMS for 1 minute duration is equivalent to 3000 VAC RMS for 1 second duration.
