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.

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
