Otherwise 5 seconds with soldering iron. 2) Device considered a two terminal device with all Input pins (Anode and Cathode) shorted together and all Output pins (VCC, GND and Output) shorted together. 3) CURRENT TRANSFER RATIO is defined as the ratio of output collector current, IO, to the forward LED input current, IF, times 100%. 4) CMH is the maximum tolerable common mode transient to assure the output will remain in a HIGH logic state (ie. VO > 2.0 V). 5) CML is the maximum tolerable common mode transient to assure the output will remain in a LOW logic state (ie. VO < 0.8 V). 6) In applications where dv/dt may exceed 50,000 V/μS (such as static discharge) a series resistor, RCC, should be include to protect the detector IC from destructively high surge currents. The recommended value is RCC = 1V/(0.6 * IF) mA. SELECTION GUIDE PART # PART DESCRIPTION 66326-001 Commercial 66326-101 Screened MICROPAC INDUSTRIES, INC. OPTOELECTRONIC PRODUCTS DIVISION 725 E.
