Description

The NC7SZ38 is a single 2-Input NAND gate with open
drain output stage from Fairchild’s Ultra-High Speed
Series of TinyLogic
advanced CMOS technology to achieve ultra-high
speed with high output drive while maintaining low static
power dissipation over a very broad V
range. The device is specified to operate over the 1.65V
to 5.5V V

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.
