NC7S14
TinyLogic
HS Inverter with Schmitt Trigger Input
General Description
The NC7S14 is a sing le high perfo rmance CMOS Inverter
with Schmitt Trigger input. The circuit desig n provide s hysteresis between the positive-going and negative going
input thresholds thereby improving noise margins.
Advanced Silicon Gate CMOS fabrication assures high
speed and low pow er circuit operation over a broad V
CC
range. ESD protectio n diodes inherently gu ard both input
and output with respect to the V
CC
and GND rails.
Features
■ Space saving SOT23 or SC70 5-lead package
■ Schmitt input hysteresis:
> 1V typ
■ High speed: t

■ Broad VCC operating range: 2V – 6V
■ Balanced propagatio n delay s
■ Specified for 3V operation

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
(Note 2)
Note 1: Absolute maximum ratings are those values beyond which damage
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 ou tput/inp ut loadi ng varia bles. Fairchild does no t
recommend operat ion of circuits outside the dat abook specifications.
Note 2: Unused inputs must be held HIGH or LOW. They ma y not float.

) at no output
loading and operating at 50% duty cycle. (See Figure 2.) C
PD
is related to I
