UHS Dual Buffer with Schmitt Trigger Inputs
NC7WZ17
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 VCC operating range. The
device is spe cified to operate over the 1.6 5V to 5.5V VCC
range. The inputs and outputs are high impedance when
VCC is 0V. Inputs tolerate voltages up to 7V independent of
VCC operating voltage. Schmitt trigger inputs typically
achieve 1V hysteresis between the positive going and neg-
ative going input threshold voltage at 5V VCC.
Features
■Space saving SC70 6-lead 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
■Matches the performance of LCX when operated at
3.3V VCC
■Power down high impedance inputs/outputs
■Overvoltage tolerant inputs facilitate 5V to 3V translation
■Patented noise/EMI reduction circuitry implemented

AC Electrical Characteristics
Note 3: CPD is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (ICCD) at no output
loading and operating at 50% duty cycle. (See Figure 2.) CPD is related to ICCD dynam ic operating current by th e ex pression:
ICCD = (CPD)(VCC)(fIN) + (I CCstatic).
