DESCRIPTION
The ISTS200_ series of transmissive
photointerrupters are single channel switches
consisting of a Gallium Arsenide infrared
emitting diode coupled to a high speed integrated
circuit detector. The output incorporates a
Schmitt trigger which provides hysteresis for
noise immunity and pulse shaping. The gap in
the plastic housing provides a means of
interrupting the signal with an opaque material,
switching the output from an 'OFF' into an 'ON'
state.
FEATURES
l Output high under incident light
l Built in Schmitt trigger circuit
l Pull up resistor between V
CC
and output
l High sensitivity
l 3mm gap between LED and detector
l 0.25mm aperture over detector :-
ISTS2002, ISTS2003
APPLICATIONS
l Floppy disk drives, Copiers, Printers,
Facsimilies, VCR's, Cassette tape
Recorders, Automatic vending machines
