Working Principles

The STP16CPS05M operates based on a serial data input that controls the state of each LED output channel. The data is shifted into the internal shift register using the clock input. Once the desired data is loaded, the latch enable input updates the outputs simultaneously, ensuring synchronized illumination of the connected LEDs. The output enable input allows for turning off all LED outputs when necessary.

Detailed Application Field Plans

The STP16CPS05M finds extensive application in various fields, including: - Digital signage and advertising displays - Scoreboards and stadium displays - Information boards and public transportation systems - Automotive lighting and instrument clusters - Industrial control panels and equipment
