hello,
        i am building a circuit which requires a high speed BCD counter with
clear.  it must be able to handle frequencies up to 40 MHz.  the one that 
comes to mind is the 74s196 which according to a TTL data book can handle 
up to 100 MHz at clock 1 and 50 MHz at clock 2.  fine, but here's the catch,
it must be CMOS.  oh no...
	as much as i have tried i can't seem to locate a cd74hc196, my question
is, does anyone know if this even exists?  and if not, is there a chip out
there which is comparable.  i have very limited access to data books so any
responses are very much appreciated.
        while i'm on the topic of appreciation, thanks to the many responses
i received on my last posting,(schmitt trig. configurations).

		thanks again,

		brian wybaillie
