[sdiy] CMOS schmitt trigger question

[harry bissell]

You can parallel gates in the SAME CMOS package...
for higher current drive vs larger input capacitance
(load).

Don't do this with different packages... the matching
is not good enough.

I have usually not seen this done with the schmitt
trigger type gates. I don't know if the gate to gate
matching is as good ???
