| SDP86XX Optoschmitt Detector 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 INFRA--6.TIF DESCRIPTION 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 ki (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.
