... ON Semiconductor Confidential Proprietary SCCW77400A / SCCW77400B Product Preview The SCCW77400 is an ASIC for reflective optical switch. Embedded with an infrared light emitting diode (LED) and a phototransistor, this ASIC controls the infrared emitter, read the detector-signal and convert it into a digital signal. The reflective interrupter will be implemented into mobile communication devices. ...
