. Ideal for applications where battery
life is critical, this product is designed for ultra low power
consumption within the V
CC
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.
