either differential or single ended input levels. The clock enable is
internally synchronized to eliminate runt pulses on the outputs
during asynchronous assertion/deassertion of the clock enable
pin. Outputs are forced LOW when the clock is disabled. A sepa-
rate output enable pin controls whether the outputs are in the
active or high impedance state.
Guaranteed output and part-to-part skew characteristics make
the ICS8305I ideal for those applications demanding well de-
fined performance and repeatability.
