| NC7SV74 TinyLogic ULP-A D-Type Flip-Flop with Preset and Clear June 2003 Revised March 2004 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.
