Notes:
1. Bypassing of the power supply line is required, with a 0.1
µF
ceramic disc capacitor adjacent to each optocoupler as illustrated in Figure 15. Total
lead length between both ends of the capacitor and the isolator pins should not exceed 20 mm.
2. Device considered a two terminal device: pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7, and 8 shorted together.
3. The t
PLH
propagation delay is measured from the 3.75 mA point on the falling edge of the input pulse to the 1.5 V point on the rising edge of the
output pulse.
4. The t
PHL
propagation delay is measured from the 3.75 mA point on the rising edge of the input pulse to the 1.5 V point on the falling edge of the
output pulse.
5. The t
ELH
enable propagation delay is measured from the 1.5 V point on the falling edge of the enable input pulse to the 1.5 V point on the rising edge
of the output pulse.
6. The t
EHL
enable propagation delay is measured from the 1.5 V point on the rising edge of the enable input pulse to the 1.5 V point on the falling edge
of the output pulse.
7. CM
H
is the maximum tolerable rate of rise of the common mode voltage to assure that the output will remain in a high logic state (i.e., V
OUT
> 2.0 V).
8. CM
L
is the maximum tolerable rate of fall of the common mode voltage to assure that the output will remain in a low logic state (i.e., V
OUT
< 0.8 V).

10. No external pull up is required for a high logic state on the enable input. If the V
E
pin is not used, tying V
E
to V
CC
will result in improved CMR
performance.
11. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage of
≥
4500 for one second (leakage detection
current limit, I
i-o
≤
5
µA).
12. t
PSK
is equal to the worst case difference in t
PHL
and/or t
PLH
that will be seen between units at any given temperature within the operating condition
range.
13. See application section titled “Propagation Delay, Pulse-Width Distortion and Propagation Delay Skew” for more information.
