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
the US8 package. The device is fabri cated with advanced
CMOS technology to achie ve ultra high speed with high
output drive while maintaining low static power dissipation
over a very broad V
specified to operate over the 1.65V to 5.5V V
inputs and outputs are h igh impedance when V
Inputs tolerate voltages up to 7V inde pe nde nt o f V
ating voltage. Schmitt trigger inputs typically achieve 1V
hysteresis between the positive going and negati ve going
input threshold voltage at 5V V
operating range. The device is
