ULP-A Buffer with 3-STATE Output
General Description
The NC7WV125 is a single buffer with 3-STATE output
from Fairchild’s Ultra Low Power-A (ULP-A) Series of
TinyLogic
. ULP-A is ideal for applications that require
extreme high speed, high drive and low po wer. This product is designed f or wide low voltage oper atin g ran ge (0.9V

class low power operation.
The NC7WV125 is uniquel y designed for op timized power
and speed, and is fabricated with an advanced CMOS
technology to achieve high-speed operation while maintaining low CMOS power dissipation.
