Photo Switch

１. Product Overview
CPS253AL/BL are the digital output photo ICs that integrate photodiode, amplifier circuit, Schmitt trigger
circuit, and output transistor on single chip. They have less sensitivity variation due to power supply
even over a wide operating supply voltage range.
The output type is open collector, and CPS253AL goes high level when light is input, while CPS253BL
goes low level when light is input.

２. Features■

Compact chip dimensions (package size X:2.0mm Y:2.0mm)■

High-speed response (max.): CPS253AZ: tpLH =5μs, tpHL =10μs CPS253BZ: tpLH =10μs, tpHL =5μs■

Wide operating supply voltage range: 3.0V to 13.2V■

Threshold irradiance independent of supply voltage■

Digital output (open collector)

３. Applications
Copy machines / Printers / Facsimiles / ATMs / Vending machines / Amusement equipment
