Description

The NC7WZ14 is a dual inverter with Schmitt trigger input
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
very broad V
operate over the 1.65V to 5.5V V
outputs are high-impedance when V
tolerate voltages up to 7V independent of V
voltage. Schmitt trigger inputs achieve typically 1V
hysteresis between the positive-and negative-going input
threshold voltage at 5V.

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.
