I need to implement some additional output pins for PIC MCU to switch on and off transistors which in turn ON/OFF MOSFETs via opto-couplers. I need 12 channels, so plans to cascade 2 8 bit shift registers.
I felt by reading data sheets that, I can use either 74HC164 or 74HC4094.
What is the basic difference between those two chips? both are serial in parrellel outs? what is the plus point in each case?
One is 'shift latch register'. How it effects practically in application?
please
Thanks
