Each OLH 300 has a light emitting diode and an integrated photodiode transistor detector mounted and coupled in a ceramic substrate inside a hermetic TO-5 package providing 1000 Vdc electrical isolation between input and output. The integrated photo-diode transistor improves switching speed by orders of magnitude as compared to standard photo transistors, by reducing the base to collector capacitance. The internal shield provides excellent common-mode immunity performance. 1000 Vdc electrical isolation High-Speed, 1 Mbit/s typical Open collector output 300 Khz bandwidth TO - 5 hermetic package Similar to 6N135/136, 4N55 Radiation tolerant 100% hi-rel screening are offered NOTES: 1. Measured between pins 1,2 and 3 shorted together and pins 5,6 and 7 shorted together. TA = 25 C and duration = 1 second. 2. Current transfer ratio is define as the ratio of output collector current, Ic to the forward LED current, IF times 100% Absolute Maximum Ratings Couple Input to Output Isolation Voltage 1 Storage Temperature Range Operation Temperature Range Lead Temperature 1.6 mm from case for 10 sec.
