TinyLogic
UHS Dual Buffer with Schmitt Trigger Inputs
General Description
The NC7WZ17 is a dual buffer with Schmitt trigger inputs
from Fairchild’s Ultra High Speed Series of TinyLogic
in
the SC70 6-lead 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
operating voltage. Schmitt trigger inputs typically
achieve 1V hysteresis between the positive going and neg-
ative going input threshold voltage at 5V V
CC
.
