Description
The NC7SZ126 is single buffer with three-State output
from Fairchild’s Ultra-High Speed (UHS) series 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 broad V
CC
operating range. The
device is specified to operate over the 1.65V to 5.5V
V
CC
operating 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
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.
