NC7SP74
TinyLogic
 ULP D-Type Flip-Flop with Preset and Clear
General Description
The NC7SP74 is a single D-type CMOS Flip-Flop with pre-
set and clear from Fairchild’s Ultra Low Power (ULP)
Series of TinyLogic
. Ideal for applications where battery
life is critical, this product is designed for ultra low power
consumption within the VCC operating range of 0.9V to
3.6V.
The internal circuit is composed of a minimum of inverter
stages including the output buffer, to enable ultra low static
and dynamic power.
The NC7SP74, for lower drive requirements, is uniquely
designed for optimized power and speed, and is fabricated
with an advanced CMOS technology to achieve best in
class speed operation while maintaining extremely 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.

Battery Life vs. VCC Supply Voltage
TinyLogic ULP and ULP-A with up to 50% less power consumption can
extend your battery life significantly.
Battery Life
= (V
battery *Ibattery*.9)/(Pdevice)/24hrs/day
Where, Pdevice = (ICC * VCC) + (CPD + CL) * VCC
2 * f
Assumes ideal 3.6V Lithium Ion battery with current rating of 900mAH and
derated 90% and device frequency at 10MHz, with CL = 15 pF load
