Description
The TSL1402R linear sensor array consists of two sections of 128 photodiodes each and associated charge
amplifier circuitry, aligned to form a contiguous 256 × 1 pixel array. 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 requiring only a serial-input pulse (SI) and a clock.
The TSL1402R 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. Integration time is calculated as follows:
tint(min) = (256 18) y clock period + 20 ms
where 256 is the number of pixels in series, 18 is the required logic setup clocks, and 20 ms is the pixel charge transfer time (tqt)
2. SI must go low before the rising edge of the next clock pulse.
