Description
The NC7SZ125 is a single buffer with three-state output
®
from Fairchild's Ultra-High Speed (UHS) of TinyLogic .
The device is fabricated with advanced CMOS
technology to achieve ultra high speed with high output
drive while maintaining low static power dissipation over
a very broad V
CC
operating range. The device is
specified to operate over the 1.65V to 5.5V range. The
inputs and output are high impedance above ground
when V
CC
is 0V. Inputs tolerate voltages up to 6V
independent of V
CC
operating voltage. The output
tolerates voltages above V
CC
when in the 3-STATE
condition.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.
