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 SFH6318T 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 SFH6319T 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.
