NC7SZ126
TinyLogic
™
UHS Buffer with 3-STATE Output
General Description
The NC7SZ126 is a single buffer with 3-STATE output from
Fairchild’s Ultra High Speed Series of Tinylogic. The device
is fabricated with advanced CMOS technology to achieve ul-
tra high speed with high output drive while maintaining low
static power dissipation over a very broad V
CC
operating
range. The device is specified to operate over the 1.8V to
5.5V range. The inputs and output are high impedance
above ground when V
CC
is 0V. Inputs tolerate voltages up to
6V independent of V
CC
operating voltage. The output toler-
ates voltages above V
CC
in the 3-STATE condition.
