74F14 Hex Inverter Schmitt Trigger
74F14
Hex Inverter Schmitt Trigger
General Description
The 74F14 contains six logic inverters which accept stan-
dard TTL input signals and provide standard TTL output
levels. They are capable of transforming slowly changing
input signals into sharply defined, jitter-free output signals.
In addition, they have a greater noise margin than conven-
tional inverters.
Each circuit contains a Schmitt trigger followed by a Dar-
lington level shifter and a phase splitter driving a TTL
totem-pole output. The Schmitt trigger uses positive feed
back to effectively speed-up slow input transition, and pro-
vide different input threshold voltages for positive and neg-
ative-going transitions. This hysteresis between the
positive-going and negative-going input thresholds (typi-
cally 800 mV) is determined internally by resistor ratios and
is essentially insensitive to temperature and supply voltage
variations.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
Note 1: Absolute maximum ratings are values beyond which the device
may be damaged or have its useful life impaired. Functional operation
under these conditions is not implied.
Note 2: Either voltage limit or current limit is sufficient to protect inputs.
