NC7SZ125 TinyLogic£ UHS Buffer with 3-STATE Output

NC7SZ125
TinyLogic£ UHS Buffer with 3-STATE Output
General Description
The NC7SZ125 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 ultra high speed with high output drive while main-
taining low static power dissipation over a very broad V
CC
operating range. The device is specified to operate over
the 1.65V to 5.5V range.
The inputs and output are high impedance above ground
when V
CC
is 0V. Inputs tolerate voltages up to 6V indepen-
dent of V
CC
operating voltage. The output tolerates volt-
ages above V
CC
when in the 3-STATE condition.

Note 2:
Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside datasheet specifi-
cations.
Note 3:
Unused inputs must be held HIGH or LOW. They may not float.
