HST Inverter
General Description
The NC7ST04 is a single high performance CMOS
Inverter, with TTL-compatible inputs. Advanced Silicon
Gate CMOS fabrication assures high speed and low power
circuit operation. ESD protection diodes inherently guard
both input and output with respect to the V
CC
and GND
rails. High gain circuitry offers high noise immunity and
reduced sensitivity to input edge rate. The TTL-compatible
input facilitates TTL to NMOS/CMOS interfacing. Device
performance is similar to MM74HCT but with ½ the output
current drive of HC/HCT.

Note 1:
Absolute Maximum Ratings are those values beyond which dam-
age to the device may occur. The databook specifications should be met,
without exception, to ensure that the system design is reliable over its
power supply, temperature, and output/input loading variables. Fairchild
does not recommend operation of circuits outside the databook specifica-
tions.
Note 2:
Unused inputs must be held HIGH or LOW. They may not float.

C
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
CCD
dynamic operating current by the expression:
