HST 2-Input NAND Gate
General Description
The NC7ST00 is a single 2-In put high pe rform ance C MOS
NAND Gate, with TTL-compatible inputs. Advanced Silicon
Gate CMOS fabrication assures high speed and low power
circuit operation. ES D protection diodes inherently g uard
both inputs and outpu t 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 inte rfacing. Device
performance is similar to MM74HCT but with 1/2 the output
current drive of HC/HCT.

Conditions
(Note 2)
Note 1: Absolute Maximum Ratings a re those va lues beyon d which d amage to the device may occu r. The databook specificati ons should be met ,
without exception, to ensure that the design is reliable over its power supply, temperature, and output/input loading variables Fairchild does not recommend operation of circuits outside the da t abook specifications.
Note 2: Unused inputs must be held HIGH or LOW. They ma y not float.
