† 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.

The TSL401 linear sensor array consists of a 128 × 1 array of photodiodes and associated charge amplifier circuitry. The pixels measure 63.5 mm (H) × 50 mm (W) with 63.5-mm center-to-center spacing and 13.5 mm between pixels. Operation of TSL401 is simplified by internal logic requiring only a serial input (SI) signal and a clock.
