The sections are aligned to form a contiguous 768 × 1 pixel array. The device incorporates a pixel data-hold function that provides simultaneous integration-start and integration-stop times for all pixels. 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 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. The device operates from a single 5-V power source. The two sections of 384 pixels each can be read out separately or can be cascaded to provide a single output for all 768 pixels (see Figure 9). The TSL1406RS is the same device mounted in a shorter package. These devices are intended for use in a wide variety of applications including mark and code reading, OCR and contac...
