TinyLogic
ULP Buffer with 3-STATE Output
General Description
The NC7WP125 is a dua l buffer w ith 3-S TATE output 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 NC7WP125, for lower drive requiremen ts, is uniquely
designed for optimi zed po wer and speed, and is fab ri cat ed
with an advanced CMOS technology to achieve best in
class speed operation while maintaining extremely low
CMOS power dissipation.
