TinyLogic
UHS Triple Buffer
with Schmitt Trigger Inputs
General Description
The NC7NZ17 is a triple buffer with Schmitt trigger inputs
from Fairchild’s Ultra High Speed Series of TinyLogic
in
the US8 package. The device is fabricated with advanced
CMOS technology to achieve ultra 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 1.65V to 5.5V V
CC
range. The
inputs and outputs are high impedance when V
CC
is 0V.
Inputs tolerate voltages up to 7V independent of V
CC
oper-
ating voltage. Schmitt trigger inputs typically achieve 1V
hysteresis between the positive going and negative going
input threshold voltage at 5V V
CC
.

Note 1:
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 2:
Unused inputs must be held HIGH or LOW. They may not float.

) at no output
loading and operating at 50% duty cycle. (See Figure 2.) C
