TinyLogic
ULP Triple Buffer
General Description
The NC7NP34 is a triple buffer 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 consumption within the V
CC
operating
range of 0.9V to 3.6V V
CC
.
The internal circuit is composed of 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 with an advanced CMOS technology to
achieve high speed, low noise operation while maintaining
extremely low CMOS power dissipation.
