Im about to put an RGB fader circuit together and it requires the 74hct93. I have quite a few of the 74hc595's. I thought since they are close in name and both shift registers I would ask.

74hc595 http://html.alldatasheet.com/html-pdf/243947/STMICROELECTRONICS/M74HC595B1R/1948/1/M74HC595B1R.html

74hct93 http://html.alldatasheet.com/html-pdf/15674/PHILIPS/74HCT93/497/2/74HCT93.html

  • \$\begingroup\$ We will need links to datasheets. Also, in the title of your Q you said 74hct793, but later you said 74hct93. Which is it? \$\endgroup\$ – user3624 Aug 26 '13 at 18:56
  • \$\begingroup\$ Seriously? By this logic, there should only be one IC ever. \$\endgroup\$ – Connor Wolf Aug 27 '13 at 4:31
  • \$\begingroup\$ NOt really a helpful comment Connor Wolf. Stop by often to make new users feel like dicks? You could have just not posted. Maybe choose that option in the future? \$\endgroup\$ – user28025 Sep 4 '13 at 18:25

No, they are not interchangeable. Not even close. The '93 isn't a shift register.
