hey, so i'm using a hex inverter for the first time in this circuit (bottom left of these 4 images):
notice the triangular images for the hex inverter. here is the datasheet for the inverter: http://focus.ti.com/lit/ds/symlink/sn74ac04.pdf
i have no idea what this component is doing here, first of all. more importantly, i don't know how to figure out what pins correspond to what part of the symbol in the circuit diagram. perhaps someone would take the time to explain these things to me?
thank you for your time
