DESCRIPTION
Very high current ratio together with 4000 VRMS isolation are
achieved by coupling an LED with an integrated high gain
photo detector in a SOIC-8 package. Separate pins for
the photo diode and output stage enable TTL compatible
saturation voltages with high speed operation.
Photodarlington 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 kΩ pull-up resistor.
The SFH6319 is best suited for low power logic
applications involving CMOS and low power TTL. A 400 %
current 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 grounding would prevent damage further and / or
degradation which may be induced by ESD.
