Decade counter w/ hex inverter - inverted LED output?
I want six LEDs sequentially counting from the 4017 decade counter and invert their states. For example, during the decade count, instead of the output LEDs being: off-off-on-off-off-off, I want the option to invert their states to be: on-on-off-on-on-on.

It looks like I need to use a 4049 hex inverter to the output of the decade counter to do this. I guess I connect each LED to its six outputs to invert their states. Seems it would work. Do I just connect a momentary switch to its supply voltage (pin 1) to invert the LEDs on its output? I'm going to experiment with this...
