 ULP Triple Buffer

General Description

The NC7NP34 is a triple buffer from Fairchild’s Ultra Low
Power (ULP) Serie s of TinyLogic
where battery life is critical, this product is designed for
ultra low power consumption within the V

range of 0.9V to 3.6V V

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 NC7NP34 is designed for optimized power and speed,
and is fabricated w ith an advanced CMOS tech nology to
achieve high speed, low noi se operat ion while mai ntaining
extremely low CMOS power dissipation.

. Ideal for applicat ions
