Working Principles

The MM74HC597N operates by receiving serial data through the Serial Data Input (DS) pin. The data is then shifted into an internal shift register on each rising edge of the Clock Input (CP). The Latch Enable Input (LE) signal determines when the parallel output is updated. When LE is high, the current data in the shift register is latched and transferred to the parallel output pins. The parallel data can then be accessed simultaneously from the Q0 to Q7 pins.
