DIY_EFI Digest V5 #123

[Scotty Grover]

'Scuse me for butting in, but a CD4049 (Inverting) or CD4050 (Non-inverting) may work
better than a 74C14.  The CD's (Powered by 5V) accept 15V at their inputs.


> I don't think the 74C14 Schmitt trigger would like 12V input if it's
> running from a 5V supply rail. The Schmitt trigger connects to the
> inputs of the uC, which shares the regulated 5V supply.
