NC7SZ74
TinyLogic UHS D-Type Flip-Flop with Preset and Clear
General Description
The NC7SZ74 is a single D-type CMOS Flip-Flop with pre-
set and clear from Fairchild’s Ultra High Speed Series of
TinyLogic in the space saving US8 package. The device
is fabricated with advanced CMOS technology to achieve
ultra high speed with high output drive while maintaining
low static power dissipation over a very broad VCC operat-
ing range. The device is specified to operate over the
1.65V to 5.5V VCC range. The inputs and output are high
impedance when VCC is 0V. Inputs tolerate voltages up to
7V independent of VCC operating voltage. The output toler-
ates voltages above VCC in the 3-STATE condition.
The signal level applied to the D input is transferred to the
Q output during the positive going transition of the CLK
pulse.
