Hollister,
The specification for the CLK IN range refers to what voltage range the hardware can detect. It is not a programmable voltage level.
Essentially this means that you could input a TTL specific clock or a CMOS specific clock and the 6541 could use either signal as a clocking source.
I hope this helps!
