TinyLogic
ULP Dual 2-Input NAND Gate
General Description
The NC7WP00 is a dual 2-input NAND Gate 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 con sumption w ithin t he
V
operating range of 0.9V to 3.6V.
CC
The internal circ uit is composed o f a minimum of inverter
stages including the output buffer, to enable ultra low static
and dynamic power.
The NC7WP00 is designed for optimized power and
speed, and is fabricat ed with an advan ced CM OS techn ology to achieve high speed operation while maintaining
extremely low CMOS power dissipation.
