 ULP-A 2-Input NAND Gate

(Open Drain Output)

General Description

The NC7SV38 is a single 2-Input NAND Gate with open
drain output stage from Fairchild’s Ultra Low Power-A
(ULP-A) series of TinyLogic
tions that require e xtreme high speed, hig h drive and low
power. This product is designed for a wide low voltage
operating range (0.9V to 3.6V V

require more drive and speed than the TinyLogic ULP
series, but still offer best in class low power operation.

The NC7SV38 is uniquel y designed for optimi zed power
and speed, and is fabricated with an advanced CMOS
technology to achieve high-speed operation while main­taining low CMOS power dissipation.
