Hi
For the ones that are not able to get DIP I have in the past installed a
SOIC on a repair by using wires I saved from resistors that I had to cut and
soldered them into the holes, formed them, put the SOIC in place and
subsequently connected to the IC. Since it is only one it can be done in ten
minutes.
Before any new boards get ordered I would change the layout. Surface mount
is no fun but if a hole is placed on each side so the device can be held in
place with a wire before soldering (third hand) it is very easy. I am 68!

Hi
The 74ACT175 came about when the 74AC175's went away at Mouser. The SOIC
packaged 74ACT175 is the closest sub for those wanting to do a "one stop
shop" at Mouser for all the parts on the board.
Of course if you do get the SOIC part you need something to kludge it onto
the board with, so it's not really one stop.

Claude,
No problem you are on the list, the 74AC175PC is correct chip, not
74ACT175PC.

Hello !
I know I'm a bit late, but is it still possible to order three boards, and
have
shipped to Canada ?
I can program my own PIC's and have access to 74ACT175.
Also, I would be willing to program chips for other Time Nuts if it can
help
someone.
Thanks !
Claude
