DESCRIPTION
The 66330 high voltage isolator consists of an 850 nm LED optically c oupled to a photodiode driven detector. The isolator provides high isolation and fast switching speeds over the specified temperature range of -40ºC to +100ºC.The isolator is built with hermetic components internally optically coupled and encased in a high temperature outer PPS plastic housing.

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 66330-001 Commercial 66330-101 Screened
