Referencing the above image, I have a few a questions.

1) I think CLK means clock input; does CLR perhaps mean clear?
2) What exactly is the role of the output buffer?
3) I'm confused as to how the control logic exactly functions and what components it would be constructed from. I'm not looking to use an MCU.

You can find an alternate description of this circuit here.

clk is clock and clr is clear.

the output buffer holds the result of the conversion and shields the down stream digital from the act of counting.
