Schmitt Triggers...

[Ginsly]

The PWM is on my list to build, and it requires a CD40106 Schmitt Trigger. I plan on getting the necessary chip, but I oddly have a different ST chip, an NTE74ls14.

I'm not familiar with this kind of component, and was wondering - could one sub for the other in this schematic? I've looked at both datasheets but I'm not sure what to look for in this case.

Here's the project:

At a glance, may work if you only use pin1-7.
Throw it in the BB and find out.
