DESCRIPTION
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.
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.
FEATURES
• High current transfer ratio, 300 %
• Low input current, 0.5 mA
• High output current, 60 mA
• TTL compatible output, VOL = 0.1 V
• Adjustable bandwidth access to base
• Material categorization: for definitions of
compliance please see www.vishay.com/doc?99912
APPLICATIONS
• Logic ground isolation - TTL / TTL, TTL / CMOS,
CMOS / CMOS, CMOS / TTL
• EIA RS 232C line receiver
• Low input current line receiver long lines, party lines
• Telephone ring detector
• Line voltage status indication - low input power
dissipation
• Low power systems - ground isolation
