It has a minimum of 1768 VRMS isolation from input to output. The device consists of four phototransistors as detectors. Each channel is individually controlled. The optocoupler is housed in a SOT-223/10 package. All the cathodes of the input LEDs and all the collectors of the output transistors are common enabling a pin count reduction from 16 pins to 10 pins a significant space savings as compared to four channels that are electrically isolated individually. and in APPLICATIONS • Telecommunication • SMT • PCMCIA • Instrumentation AGENCY APPROVALS • UL1577, file no.
