Very expensive pic programming over where you are ...
the MAX chip uses an active low input, so just wanted to check if it could be connected directly to the max, or if it needs inverted.
Yes, the switch can be connected directly to the MAX. A switch normally doesn't care if it switches ground or VSS. Debouncing is accomplished in the chip.
Having to switch positive potential the OP might refer to ATMEL U6032B which offers more options (and more external circuitry) and is manufactured in a DIP-08 package.
Using either one the OP won't have to throw a case of beer.
