Description
The NC7WZ17 is a dual buffer with Schmitt trigger
inputs from Fairchild's Ultra-High Speed (UHS) series
of TinyLogic® products. 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
operating range. The device is specified to operate
over the 1.65V to 5.5V V
outputs are high-impedance when V
tolerate voltages up to 7V, independent of V
operating voltage. Schmitt trigger inputs achieve 1V
typical hysteresis between the positive- and negativegoing 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.
