I sucessfully use 74HC and 74HCT familty to at least 30 - 40MHz. It can often
be pushed to just above 50MHz. If you want to got faster, the 74ACT family can
be used as buffers to beyond 100MHz, but counters and shift registers in that
technology don't seem to go much beyond 80MHz in my experience

Subject: LF: 4060 Divider
I would like to use the M74HC4060 as a 'divide-by-64' signal source. Can
anyone tell me the upper limit for xtals that this chip can handle? My xtal
will be on 8.750000; I fear that the upper limit may be around 4-6 MHz?
