IS4N46 IS4N45 LOW INPUT CURRENT DARLINGTON OUTPUT OPTICALLY COUPLED ISOLATOR APPROVALS l UL recognised, File No. E91231 Dimensions in mm 2.54 7.0 6.0 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 OPTION SM OPTION G SURFACE MOUNT 7.62 1 6 2 5 3 4 1.2 7.62 6.62 7.62 4.0 3.0 13 Max 0.5 3.0 0.5 3.35 0.26 ABSOLUTE MAXIMUM RATINGS (25C unless otherwise specified) Storage Temperature -55C to + 150C Operating Temperature -55C to + 100C Lead Soldering Temperature (1/16 inch (1.6mm) from case for 10 secs) 260C INPUT DIODE Forward Current Reverse Voltage Peak Forward Current (1s pulse, 300pps) Power Dissipation 60mA 6V 3A 100mW OUTPUT TRANSISTOR Output Voltage ( pin 5 - 4 ) VO Emitter-baseVoltage (pin 4 - 6) Power Dissipation 55V 7V 200mW POWER DISSIPATION 0.6 0.1 10.46 9.86 1.25 0.75 0.26 10.16 ISOCOM COMPONENTS LTD Unit 25B, Park View Road West, Park View Industrial Estate, Brenda Road Hartlepool, Cleveland, TS25 1YD Tel: (01429) 863609 Fax :(01429) 863581 11/12/00 Total Power Dissipation 260mW ISOCOM INC 1024 S.
