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 products‚ in 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 V
CC
) 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 technol-
ogy 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.
