GENERAL DESCRIPTION
The 83904-02 is a low skew, high performance 1-to-4 Crystal-to-
LVCMOS Fanout Buffer. The 83904-02 has selectable single-ended
clock or two crystal-oscillator inputs. There is an output enable to
disable the outputs by placing them into a high-impedance state.
Guaranteed output and part-to-part skew characteristics
make the 83904-02 ideal for those applications demand-
ing well defi ned performance and repeatability.
