General Description

The NC7SP38 is a single 2-Input NAND Gate with
open drain output stage from Fairchild’s Ultra Low
Power (ULP) Series of TinyLogic
where battery life is critical, this product is designed for
ultra low power consumption within the V
range of 0.9V to 3.6V V

CC

The internal circuit is composed of a minimum of inverter
stages including the output buffer, to enable ultra low
static and dynamic power.

The NC7SP38, for lower drive requirements, is uniquely
designed for optimized power and speed, and is fabri­cated with an advanced CMOS technology to achieve
best in class speed operation while maintaining
extremely low CMOS power dissipation.

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.
