NC7SV74 TinyLogic ULP-A D-Type Flip-Flop with Preset and Clear
June 2003 Revised April 2005
NC7SV74 TinyLogic ULP-A D-Type Flip-Flop with Preset and Clear
General Description
The NC7SV74 is a single D-type CMOS Flip-Flop with preset and clear from Fairchild's Ultra Low Power-A (ULP-A) Series of TinyLogic in both the space saving US8 and MicroPak packages. ULP-A is ideal for applications that require extreme high speed, high drive and low power. This product is designed for a wide low voltage operating range (0.9V to 3.6V VCC) and applications that require more drive and speed than the TinyLogic ULP series, but still require low power consumption. The NC7SV74 is uniquely designed for optimized power and speed, and is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining low CMOS power dissipation. 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: IO Absolute Maximum Rating must be observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.
