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.

Note 1:
Absolute Maximum Ratings: are those values beyond which the
safety of the device cannot be guaranteed. The device should not be oper-
ated at these limits. The parametric values defined in the Electrical Charac-
teristics tables are not guaranteed at the absolute maximum ratings. The
“Recommended Operating Conditions” table will define the conditions for
actual device operation.
Note 2:

Note 3:
Unused inputs must be held HIGH or LOW. They may not float.
