TinyLogic
UHS Inverter with Schmitt Trigger Input
General Description
The NC7SZ14 is a single Inverter with Schmitt Trigger
input from Fairchild's Ultra High Speed Series of
TinyLogic
. 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 input and
output are high impedance when V
CC
is 0V. Inputs tolerate
voltages up to 6V independent of V
CC
operating 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-
tion 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

) at no output
loading and operating at 50% duty cycle. (See Figure 2.) C

is related to I
