Description

The NC7SZ34 is a single buffer from Fairchild’s Ultra­High Speed (UHS) series of TinyLogic
fabricated with advanced CMOS technology to achieve
ultra-high speed with high output drive, while
maintaining low static power dissipation over a broad
V

operating range of 1.65V to 5.5V VCC. The inputs

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.
