ULP Triple Inverter
with Schmitt Trigger Input
General Description
The NC7NP14 is a triple inverter with Schmitt trigger
input from Fairchild’s Ultra Low Power (ULP) Series of
TinyLogic
. Ideal for applications where battery life is criti-
cal, this product is design ed for ultra low power cons umption within the V
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 NC7NP14 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.
operating range of 0.9V to 3.6V VCC.
