The device incorporates a pixel data-hold function that provides simultaneous-integration start and stop times for all pixels. The pixels measure 63.5 μm by 55.5 μm with 63.5-μm center-to-center spacing and 8-μm spacing between pixels. Operation is simplified by internal logic that requires only a serial-input (SI) pulse and a clock. 1 2 3 4 5 6 7 8 9 10 11 12 13 VPP SI1 HOLD1 CLK1 GND AO1 SO1 SI2 HOLD2 CLK2 SO2 AO2 VDD The device is intended for use in a wide variety of applications including mark and code reading, OCR and contact imaging, edge detection and positioning, and optical encoding.
