2 Channel Optocoupler, Darlington Output, SOIC, 8 Pins, 20mA, 3.75kV, 500% - 

HCPL-0731-000E is a dual-channel low input current, high-gain optocoupler. It contains a separated pair of GaAsP light-emitting diodes optically coupled to a pair of integrated high-gain photodetectors. This provides extremely high current transfer ratio and excellent input-output common mode transient immunity. A separate pin for the photodiodes and first gain stages (VCC) permits lower output saturation voltage and higher speed operation than possible with conventional photo-Darlington type optocouplers. Applications include digital logic ground isolation, telephone ring detector, level shifting, EIA RS-232C line receiver, polarity sensing, low input current line receiver – long line or party line, microprocessor bus isolation, current loop receiver, line voltage status indicator – low input power dissipation. Safety approvals include UL recognized – 3750V rms for 1 minute and 5000Vrms for 1 minute, CSA approved.
