Hermetic SMT package
Electrical parameters guaranteed over
-55
C to +125
C ambient temp. range
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
The OLF300 is suitable for interfac-
ing 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 cus-
tom 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 com-
pared to standard photo transistors, by
reducing the base to collector capaci-
tance. The internal shield provides excel-
lent common-mode immunity perfor-
mance.
1. Measured between pins 1, 2 and 6 shorted together and pins 3, 4, and 5 shorted together. T

C and duration = 1 second.
2. Current transfer ratio is defined as the ratio of output collector current, Ic to the forward LED current, I
F
, times 100%.
