IST970T Datasheet PDF - Isocom

DESCRIPTION
The ISTS970 and ISTS971 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
● Output high under incident light
● Built in Schmitt trigger circuit
● Pull up resistor between VCC and output (ISTS970)
● Open collector output (ISTS971)
● High sensitivity
● 3mm gap between LED and detector
● 1mm aperture over detector

APPLICATIONS
● Floppy disk drives, Copiers, Printers, Facsimilies, VCRs, Cassette tape Recorders, Automatic vending machines
