The SN74LVC1G04 is a single inverter gate designed for 1.65 V to 5.5 V Vcc operations. It performs the Boolean function Y =/A. For our project we used the DBV package (SOT-23) for ease of soldering. Most of the packages for this part are available as free samples off of TI’s website, so if you choose to switch packages for your particular project it is affordable to do so.
We used this chip to invert the logic level from the supervisor enable line in order to switch an NMOS on and off. This is detailed in Rev2 of the hardware section
