Description
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.
♦
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
