hi all
i need six, 2 input nand schmitt trigger gates in a single ic.
i just don't want to use 2, cd4093 ics. Is there any such ic which i can use?
thanks for reply
Hi, Jack. Sorry to say, I believe the part you're seeking doesn't exist.
If you want to use MML (Mickey Mouse Logic), you can kludge together a one-IC
solution with a 74C14 like this:
VCC
+
|
.-.
| |
| |
'-'
| |\
A o---|<--o--|H>O- o Q
| |/
|
B o---|<--o

Q is low only when A AND B are high, and there is some hysteresis for the
second signal to change. It is slower than a standard gate, and there will be
more space and holes/pads than two ICs. I don't think this is better than two
ICs, but there it is.
Use two ICs.
Good luck
Chris
