SN74LV595A: sn74lv595a QH' Timing

Part Number: SN74LV595A

Hi,team

When QH' will output?
I can't understand from datasheet.
I want to know QH'timing because I want to connect three device with daisy chain.

thanks.

  • As shown in the simplified schematic, QH' is the eighth bit of the shift register, and is controlled by the shift register clock (SRCLK).

    You are supposed to connect it directly to the SER input of the next device in the chain (this is the same connection as between the shift register flip-flops inside the device).
