glitchless gating of the Q

signal is LOW, the input is passed to the outputs and the data

output equals the data input. When the data input is HIGH and

the /EN goes HIGH, it will force the Q

HIGH on the next negative transition of the data input. If the

data input is LOW when the /EN goes HIGH, the next data

transition to a HIGH is ignored and Q

input is not passed on to the data outputs under these

conditions. The Q

abled state as long as the /EN input is held HIGH. The /EN

input has no influence on the /Q output and the data input is

passed on (inverted) to this output whether /EN is HIGH or

LOW. This configuration is ideal for crystal oscillator applica-

tions, where the oscillator can be free running and gated on

and off synchronously without adding extra counts to the

output.
