ULP Inverter with Schmitt Trigger Input
General Description
The NC7SP14 is a single 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 designed for ultra low power consump-
tion 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 NC7SP14, for lower drive requirements, is uniquely
designed for optimized power and speed, and is fabricated
with an advanced CMOS technology to achieve best in
class speed 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.
