SN74HC165: GPIO extension for microcontroller in combination with the SN74HC595

Part Number: SN74HC165
Other Parts Discussed in Thread: SN74HC595, CD74HC299, SN74LVC1G04, SN74AHC1G04

Dear support team,

I am currently working at an GPIO extension for a microcontroller. I want to use 1 SPI Port for the extension with digital inputs and outputs. 

  • For the digital inputs I want to use the SN74HC165.
  • For the digital outputs I want to use the SN74HC595.

I have created a first draft version of the schematic and want to ask if it is possible to combine these two extension ICs together.

Could you please check if this could work?
