Low power systems - ground isolation The SFH6319 is best suited for low power logic applications involving CMOS and low power TTL. A 400 % AGENCY APPROVALS current transfer ratio with only 0.5 mA of LED current i s guaranteed from 0 C to 70 C. UL1577 Very high current ratio together with 4000 V isolation are cUL RMS achieved by coupling an LED with an integrated high gain DIN EN 60747-5-5 (VDE 0884-5) available with option 1 photo detector in a SOIC-8 package. Separate pins for CSA the photo diode and output stage enable TTL compatible saturation voltages with high speed operation. Photodarlington operation is achieved by tying the V and CC V terminals together. Access to the base terminal allows O adjustment to the gain bandwidth.
