HST 2-Input NAND Gate
General Description
The NC7ST00 is a single 2-Input high performance CMOS
NAND Gate, with TTL-compatible inputs. Advanced Silicon
Gate CMOS fabrication assures high speed and low power
circuit operation. ESD protection diodes inherently guard
both inputs 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
inputs facilitate TTL to NMOS/CMOS interfacing. Device
performance is similar to MM74HCT but with 1/2 the output
current drive of HC/HCT.

Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
(Note 2)
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 design is reliable over its power sup-
ply, temperature, and output/input loading variables Fairchild does not rec-
ommend operation of circuits outside the databook specifications.
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. Current consumption (ICCD) at
no output loading and operating at 50% duty cycle. (See Figure 2). CPD is related to ICCD dynamic operating current by the expression:
