Working Principles

The STP16DPPS05TTR operates by receiving serial data input, which is then shifted into its internal shift register. The latch enable signal transfers the data from the shift register to the output latch. The constant current driver then drives the connected LEDs based on the data stored in the latch. The output enable signal controls the output state of the IC.
