Description
These optocouplers consist of an AlGaAS LED, optically cou-
pled to a very high speed integrated photo-detector logic gate.
Single channel devices include a strobable output. This output
features an open collector, thereby permitting wired OR outputs.
The output consists of bipolar transistors in a Bi-CMOS process
for reduced power consumption. The coupled parameters are
guaranteed over the temperature range of -40°C to +85°C. A
maximum input signal of 5 mA (3 mA for the FODX6XL ver-
sions) 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 2,000V common mode.
Applications

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.
