Separate clocks are provided for the shift register. 8-Bit Shift Registers With Latched 3-State Outputs 74HC595 Feb. Separate clocks are provided for both the shift and storage register. Each part focuses on a specific integrated circuit (IC) chip.
L293D Datasheet Ti Free Output Number
The data in each register is transferred to the storage register on a positive going transition of the storage register clock input (STCP). Note the free output number zero and two of the corresponding 74HC595 to maintain the compatibility with original LiquidCrystal library. Showing 1 - 20 of 59 Application Notes. It is a relatively cheaper option compared to other display devices like LCDs. See the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
