CPS253AL/BL
Product name
Schmitt Trigger Circuit Photo IC
Overview
CPS253AL/BL is a digital output photo IC which incorporates a photodiode, amplifier, Schmitt trigger circuit and output transistor in a single chip.
The sensitivity is stable over a wide range of operating supply voltage.
The output is an open collector, CPS253AL is "H" level output at light input and CPS253BL is "L" level output at light input.
The IC package is compact and suitable for surface mount assembly.
Features
* Small transparent chip on board package(2mm x 2mm x 1.04mm, LCOB-4PIN)
* High sensitivity: 0.6uW/mm2(max)
* High speed response: CPS253AL tpLH = 3.6uS, tpHL = 6uS (max)
CPS253BL tpLH = 6uS, tpHL = 3.6uS (max)
* Wide operating supply voltage range: Vcc = 2.7 to 15V
* Threshold radiant incidence: stable over a wide range of operating supply voltage
* Digital output(open collector)
* Reflow soldering applicable
* Lead free, RoHS compliant
* Halogen-free permitted
Status
