Optoschmitt Detector
SDP86XX
DESCRIPTION
FEATURES
Side-looking plastic package
•
55¡ (nominal) acceptance angle
•
Wide sensitivity ranges
•
TTL/LSTTL/CMOS compatible
•
Buffer (SDP8600/8601/8602) or inverting
(SDP8610/8611/8612) logic available
•
Three different lead spacing arrangements
•
Mechanically and spectrally matched to
SEP8506 and SEP8706 infrared emitting diodes
•
The SDP86XX series is a family of single chip
Optoschmitt IC detectors molded in a side-looking black
plastic package to minimize the effect of visible ambient
light. The photodetector consists of a photodiode,
amplifier, voltage regulator, Schmitt trigger and an NPN
output transistor with a 10 kì (nominal) pull-up resistor.
Output rise and fall times are independent of the rate of
change of incident light. Detector sensitivity has been
internally temperature compensated. Flexibility of use is
enhanced by a choice of three different lead
configurations; in-line (SDP8601/8611), 0.05
in.(1.27 mm) offset pin circle (SDP8600/8610) and 0.10
in. (2.54 mm) offset center lead (SDP8602/8612).
Device Polarity:
Buffer - Output is HI when incident light intensity is
above the turn-on threshold level.
Inverter - Output is LO when incident light intensity is
above the turn-on threshold level.
