TinyLogic
UHS Dual Buffer
General Description
The NC7WZ16 is a dual buffer from Fairchild's Ultra High
Speed Series of TinyLogic
in the space saving 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
oper-
ating voltage.

Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
(Note 2)
Note 1: Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside datasheet specifi-
cations.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.

PD
is defined as the value of the internal equivalent capacitance which is derived from dynamic operating current consumption (I
CCD
) at no output
loading and operating at 50% duty cycle. (See Figure 2.) C
PD
is related to I

dynamic operating current by the expression:
