TinyLogic
ULP Dual 2-Input OR Gate
General Description
The NC7WP32 is a dual 2-input OR Gate 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 NC7WP32 is designed for optimized power and
speed, and is fabricated with an advanced CMOS technol-
ogy to achieve high 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:
