TinyLogic
ULP-A Buffer with 3-STATE Output
General Description
The NC7WV125 is a single buffer with 3-STATE output
from Fairchild’s Ultra Low Power-A (ULP-A) Series of
TinyLogic
. ULP-A is ideal for applications that require
extreme high speed, high drive and low power. This prod-
uct is designed for wide low voltage operating range (0.9V
to 3.6V V
CC
) and applications that require more drive and
speed than the TinyLogic ULP series, but still offer best in
class low power operation.
The NC7WV125 is uniquely designed for optimized power
and speed, and is fabricated with an advanced CMOS
technology to achieve high-speed operation while main-
taining 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:
