Dual channels enable direction of travel sensing. The transmissive housing reduces possible interference from ambient light and provides dust and dirt protection. In addition the ISTS822S, ISTS832S have 0.25mm apertures in front of the phototransistors, While the ISTS822SD, ISTS832SD have the same sized apertures in front of both emitters and phototransistors FEATURES l Single or Double apertures for High Resolution l 2.5mm Gap between LED and Detector l Dual channels "side by side" APPLICATIONS l Copiers, Printers, Facsimilies, Record Players, Cassette Decks, VCR's ABSOLUTE MAXIMUM RATINGS (25C unless otherwise specified) Storage Temperature -40C to + 85C Operating Temperature -25C to + 85C Lead Soldering Temperature (1/16 inch (1.6mm) from case for 10 secs) 260C INPUT DIODE Forward Current Reverse Voltage Power Dissipation OUTPUT TRANSISTOR Collector-emitter Voltage BVCEO Emitter-collector Voltage BVECO Collector Current IC Power Dissipation 30V 5V 20mA 75mW 50mA 5V 75mW 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 24/9/97 ISOCOM INC 720 E., Park Boulevard, Suite 104, Plano, TX 75074 USA Tel: (972) 423-5521 Fax: (972) 422-4549 DB92003-AAS/A1 ELECTRICAL CHARACTERISTICS ( TA = 25C Unless otherwise noted ) PARAMETER Input Forward Voltage (VF) Reverse Voltage (VR) Reverse Current (IR) Collector-emitter Breakdown (BVCEO) ( Note 1 ) Emitter-collector Breakdown (BVECO) Collector-emitter Dark Current (ICEO) MIN TYP MAX UNITS 1.2 3 10 30 5 100 1.6 V V A V V nA TEST CONDITION IF = 20mA IR = 10A VR = 3V IC = 1mA IE = 100A VCE = 10V Output Coupled On-State Collector Current IC ( ON ) ( Note 1 ) ISTS150, ISTS250 ( no apertures ) 250 A A A 20mA IF , 10V V CE 20mA IF , 10V VCE 20mA IF , 10V V CE ISTS822S, ISTS832S 250 (0.25mm apertures phototransistors only) ISTS822SD, ISTS832SD ( 0.25mm apertures in front of both - emitters and phototransistors ) 100 Collector-emitter Saturation VoltageVCE(SAT) ISTS150, ISTS250 ISTS822S, ISTS832S ISTS822SD, ISTS832SD 0.4 0.4 0.4 V V V 20mA IF , 125A IC 20mA IF , 125A IC 20mA IF , 50A IC Rise Time Fall Time tr tf 6 6 s s VCC = 5V, IF = 20mA, RL= 100 Note 1 Special Selections are available on request.
