Low-voltage operation photo IC
S4810, S6289
Operation at low voltage from 2.2 V
S4810 and S6289 are digital output photo ICs consisting of a photodiode, schmitt trigger circuit and output transistor, all integrated on a single chip and
molded into a visible-cut, subminiature plastic package.
Features
l Low-voltage operation: 2.2 to 7 V
l Subminiature plastic package with lens
l Low current consumption
l Open collector output
l S4810: “H” level output at light input
S6289: “L” level output at light input
Applications
l Cameras
l Tape start/end mark sensor for VTRs, cassette tape
recorders, etc.
l Optical switches
l Encoders
