General Description
The NC7SZ125 is a single buffer with 3-STATE output from
Fairchild’s Ultra High Speed Series of TinyLogic
device is fabricated wi th advanced CMOS technology to
achieve ultra high spe ed w ith h i gh out put drive while mai ntaining low static power dissipation over a very broad V
operating range. Th e device is specified to operate ov er
the 1.65V to 5.5V range.
The inputs and output ar e high impedance above gr ound
when V
dent of V
ages above V
is 0V. Inputs tolerate voltages up to 6V indepen-

Note 1: Absolute maximum ratings are DC values beyond which the devi ce
may be damage d or h ave its us eful life im pai red. Th e dat as heet sp ecific ations should be met, without exception, to ensure that the system design is
