NC7WZ17
TinyLogic UHS Dual Buffer with Schmitt Trigger Inputs
General Description
Features
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 VCC operating range. The
■ Space saving SC70 6-lead package
■ Ultra small MicroPak leadless package
■ Ultra High Speed: tPD 3.6 ns Typ into 50 pF at 5V VCC
■ High Output Drive: ±24 mA at 3V VCC
■ Broad VCC Operating Range; 1.65V to 5.5V
device is specified to operate over the 1.65V to 5.5V VCC
■ Matches the performance of LCX when operated at
3.3V VCC
range. The inputs and outputs are high impedance when
VCC is 0V. Inputs tolerate voltages up to 7V independent of
■ Power down high impedance inputs/outputs
VCC operating voltage. Schmitt trigger inputs typically
■ Overvoltage tolerant inputs facilitate 5V to 3V translation
■ Patented noise/EMI reduction circuitry implemented
achieve 1V hysteresis between the positive going and neg-
ative going input threshold voltage at 5V VCC
