You can parallel, please take a look of this web, which tell you more secret thing about SDPIF.

傻人改機 :
I don't think so, please read the above link, try to use 3-4 minutes to understanding the details, and 吳國敬 post about the internal circuit of 74HC04, if you have study the semiconductors manufacturing subject in univeristy before, you will see that picture and will get what meaning is. For the beginner diyer, you also can see this in some circuit, try to take a wide checking in our web, we have post before.
When you take a look of all material, you will know who is 傻人.
Most of the China Forum style is follow the answer of the reply from the first reply people.
這樣大量重疊並聯,大量接點、接線,jitter不用理會嗎
We put the logic as close as possible, try to make it shorter as possible.
jitter不用理會嗎
If all logic gate are indential spec. (i.e. Turn-ON-OFF) time will be the same)
For this kind of application, can be ignore.
Since T= T1 + T(n)! and n=zero.
We change to techincal point of view.
I have prepare few question to new Diyer people to study about this case ?
1. Why need to parallel ? (Ans when hit rate =1000)
2. What is the advantage? (Ans when hit rate = 1100)
3. What is the dis-advantage ? (Ans when hit rate = 1200)
4. What is the waveform looking ? Before and After ? (VERY IMPORTANT)
(Ans when hit rate = 1500)
5. How many QTY is enough ?
(Ans when hit rate = 1600)
