UHF Prescaler
The MC12090 is a high–speed D master–slave flip–flop capable of
toggle rates of over 700MHz. It was designed primarily for high–speed
prescaling applications in communications and instrumentation. This
device employs two data inputs, two clock inputs as well as
complementary Q and Q outputs. There are no SET or RESET inputs.
