To cascade multiple 74HC595 shift registers, connect the Q7' (serial out) pin of the first 74HC595 to the DS (serial data input) pin of the next 74HC595. Each subsequent 74HC595 should also have its RCLK (register clock) and SRCLK (shift register clock) pins connected to the same control signals from your microcontroller. This allows you to shift data through multiple registers in series. Ensure that all the shift registers share the same power and ground connections for proper operation.
