Threshold detector and reset generator

GENERAL DESCRIPTION The PCF1252-Xs are low-power CMOS voltage threshold detectors designed especially for supervision of microcontroller/microprocessor systems for detection of power-on/off conditions and generation of a system reset pulse. The PCF1252-X also provides a POWF (power fail) output w

CCD LINEAR IMAGE SENSOR

The TCD1252AP is a high sensitive and low dark current 2700−elements linear image sensor. The sensor can be used for facsimile, imagescanner and OCR. The device contains a row of 2700 photodiodes, which provide a 8 lines / mm (200 DPI) across a A3 size paper and a 12 lines / mm (300DPI) across a A
