General Description

The NC7WZ17 is a dual buffer with Schmitt trigger inputs
from Fairchild’s Ultra High Speed Series of TinyLogic
the SC70 6-lead package. The device is fabricated with
advanced CMOS technolog y to achieve ultra high speed
with high output drive while maintaining low static power
dissipation over a very broad V

device is specified to o perate over the 1.65V to 5.5V V
range. The input s and outputs are high impedance when

V

is 0V. Inputs tolerate voltages up to 7V independent of

CC

operating voltage. Schmitt trigger inputs typically

V

CC

achieve 1V hysteresis between the positive going and neg­ative going input threshold voltage at 5V V
