Description
The TSL1406R is a 400 dots-per-inch (DPI) linear
sensor array consisting of two 384-pixel sections,
each with its own output. 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.

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 contact imaging, edge detection and
positioning, and optical encoding.
