General Description
The NC7SZ74 is a single D-type CMOS Fli p- Flo p wi th pr eset and clear from Fairchil d’s Ultra High Speed Series of
TinyLogic
in the space saving US 8 package. T he device
is fabricated with a dvanced CMOS technolo gy to achieve
ultra high speed with high outpu t drive while maintaining
low static power dissipa tion over a very b road V
ing range. The device is specified to operate over the
1.65V to 5.5V V
impedance when V
7V independent of V
ates voltages above V
The signal level applied to the D input is transferred to the
Q output during the positive goin g transition of the CLK
pulse.
