Description
These optocouplers consist of an AlGaAS LED, optically
coupled to a very high speed integrated photo-detector
logic gate. Devices include a strobable output. This
output features an open collector, thereby permitting
wired OR outputs. The coupled parameters are
guaranteed over the temperature range of -40°C to
+85°C. A maximum input signal of 5 mA will provide a
minimum output sink current of 13 mA (fan out of 8). An
internal noise shield provides superior common mode
rejection of typically 50 kV/µs at 1,000V common mode.

Absolute Maximum Ratings
(No derating required up to 85°C)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Notes
1. The V
CC
supply to each optoisolator must be bypassed by a 0.1µF capacitor or larger. This can be either a ceramic
or solid tantalum capacitor with good high frequency characteristic and should be connected as close as possible
to the package V
CC
and GND pins of each device.
2. Enable Input – No pull up resistor required as the device has an internal pull up resistor.
3. t
PLH
– Propagation delay is measured from the 3.75 mA level on the HIGH to LOW transition of the input current
pulse to the 1.5V level on the LOW to HIGH transition of the output voltage pulse.
4. t
PHL
– Propagation delay is measured from the 3.75 mA level on the LOW to HIGH transition of the input current
pulse to the 1.5V level on the HIGH to LOW transition of the output voltage pulse.
5. t
PSK
is the worst case difference between t
PHL
and t
PLH
for any devices at the stated test conditions.
6. t
r
– Rise time is measured from the 90% to the 10% levels on the LOW to HIGH transition of the output pulse.
7. t
f
– Fall time is measured from the 10% to the 90% levels on the HIGH to LOW transition of the output pulse.
8. t
ELH
– Enable input propagation delay is measured from the 1.5V level on the HIGH to LOW transition of the input
voltage pulse to the 1.5V level on the LOW to HIGH transition of the output voltage pulse.
9. t
EHL
– Enable input propagation delay is measured from the 1.5V level on the LOW to HIGH transition of the input
voltage pulse to the 1.5V level on the HIGH to LOW transition of the output voltage pulse.
10. CM
H
– The maximum tolerable rate of rise of the common mode voltage to ensure the output will remain in the high
state (i.e., V
OUT
> 2.0 V). Measured in volts per microsecond (V/µs).
11. CM
L
– The maximum tolerable rate of fall of the common mode voltage to ensure the output will remain in the low
output state (i.e., V
OUT
< 0.8 V). Measured in volts per microsecond (V/µs).
12. Device considered a two-terminal device: Pins 1, 2, 3 and 4 shorted together, and Pins 5, 6, 7 and 8 shorted
together.
