NC7SZ74 TinyLogic UHS D-Type Flip-Flop with Preset and Clear
July 2001 Revised June 2003
NC7SZ74 TinyLogic UHS D-Type Flip-Flop with Preset and Clear
General Description
The NC7SZ74 is a single D-type CMOS Flip-Flop with preset 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 operating 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 tolerates 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.

Note 1: Absolute Maximum Ratings: are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: Unused inputs must be held HIGH or LOW. They may not float.
