Hi experts
I hate to have to ask this rather lame question, but somehow I haven't been able to come up with a good answer on the rest of the net...
I'm building a project where I need an octal buffer with a schmitt trigger.
The inputs are hooked up to phototransistor switches and the outputs will trigger the interrupts of an ATMega8 through two wired-logic OR-gates. The whole circuit is run on 5V just to clarify.
Finding such a chip doesn't seem to be a problem, however, I want to use the most commonly available chip, so I never have to worry about the supply running out (at least a while ahead). In my prototype, I'm using a 74HC7541, but my local supplier doesn't have it.. In fact I'm not quite sure where I have mine from...
Anyway, which chip would you suggest?
Thanks in advance.
