DESCRIPTION
Very high current ratio together with 2500 VAC isolation
are achieved by coupling an LED with an integrated high
gain photodetector in a SOIC-8 package. Separate pins
for the photodiode and output stage enable TTL compat-
ible saturation voltages with high speed operation. Pho-
todarlington operation is achieved by tying the VCC and
VO terminals together. Access to the base terminal
allows adjustment to the gain bandwidth.
The SFH6318 is ideal for TTL applications since the
300% minimum current transfer ratio with an LED current
of 1.6 mA enables operation with one unit load-in and
one unit load-out with a 2.2 KW pull-up resistor.

Comparative Tracking Index
The SFH6319 is best suited for low power logic applica-
tions involving CMOS and low power TTL. A 400% cur-
rent transfer ratio with only 0.5 mA of LED current is
guaranteed from 0°C to 70°C.
Caution:
Due to the small geometries of this device, it should be handled
with Electrostatic Discharge (ESD) precautions. Proper ground-
ing would prevent damage further and/or degradation which
may be induced by ESD.

2. Pin 7 open.
3. Device considered a two-terminal device: pins 1, 2, 3 and 4 shorted together and pins 5, 6, 7 and 8 shorted together.
4. Using a resistor between pin 5 and 7 will decrease gain and delay time.
5. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV /dt on the leading edge of the common mode pulse,
