MAX 2 Shield 5 .030.005 .100 MAX. .004/.006 SEATING PLANE SCHEMATIC PACKAGE OUTLINE Features Hermetic SMT package Electrical parameters guaranteed over -55C to +125C ambient temp. range Description The OLF300 is suitable for interfacing TTL to LSTTL, TTL or CMOS as well as wide bandwidth analog applications. Each OLF300 has a light emitting diode and an integrated photo-diode transistor detector mounted and coupled in a custom 8-pin hermetic flat pack 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 Similar to 6N135/136, 4N55 Radiation tolerant 100% hi-rel screenings are offered NOTES: 1. Measured between pins 1, 2 and 6 shorted together and pins 3, 4, and 5 shorted together. TA =25 C and duration = 1 second. 2. Current transfer ratio is defined as the ratio of output collector current, Ic to the forward LED current, IF , times 100%.
