DESCRIPTION The IS4N45, IS4N46 are optically coupled isolators consisting of an infrared light emitting diode and a NPN silicon photo darlington which has an integral base-emitter resistor to optimise switching speed and elevated temperature characteristics in a standard 6pin dual in line plastic package. These devices are designed to equal the 4N45, 4N46 characteristics while providing greater voltage and current capability. FEATURES l Options :10mm lead spread - add G after part no. Surface mount - add SM after part no. Tape&reel - add SMT&R after part no. l High Isolation Voltage (5.3kVRMS ,7.5kVPK ) l High Current Transfer Ratio ( 1500% typ.) l High BVCEO ( 55V min.) l Internal base-emitter resistor minimizes output leakage l Low input current 0.5mA IF APPLICATIONS l Telephone ring detector l Digital logic ground isolation l Low input current line receiver l Logic to reed relay interface l Level shifting l Interface between logic families l Line voltage status indicator - low input power dissipation
