DESCRIPTION
The SDP8604/8614 series consists of a high speed IC
molded in a side-looking black plastic package to
minimize the effect of visible ambient light. The detector
incorporates a Schmitt trigger which provides pulse
shaping and hysteresis for noise immunity. Detector
output is an NPN silicon transistor with a 10 kì
(nominal) pull-up resistor. This option eliminates the
need for an external load resistor to generate an output
signal voltage. Output rise and fall times are
independent of rate of change of incident light. Detector
sensitivity has been internally temperature
compensated. For additional output configuration
options refer to SDP8004/8014 and SDP8304/8314.

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.
