1) Just to be clear on your wording, you are saying I can combine both outputs and don't need a NAND gate?
At the time I hadn't found a single logic gate IC that did what I wanted, but after more searching I found one that meets my specs :)...
Thank-you for the advice! I might just try the NAND gate, shouldn't add that much cost, current draw, etc. Two more questions:
1) If I put a NAND gate chip on my board that has 4 NAND gates but will only be using 1 gate, if I want to save power, should I ground the rest of the unused NAND gate...
I'm making a design from a schematic that conditions a signal from a PIR circuit and goes to a microcontroller to run code when motion is sensed. At the end of the design before the signal goes to the microcontroller, there are two op amps that are used as a comparator, with both op amp outputs...
