NC7SZ05
TinyLogic
UHS Inverter (Open Drain Output)
General Description
The NC7SZ05 is a single Inverter with open drain output
stage 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.
The open drain output stage tolerates voltages up to 6V
independent of V
CC
when in the high impedance state.

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.

AC Electrical Characteristics

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
