FEATURE Industrial temperature range available (–40°C to +85°C)
DESCRIPTIONThe 74F14 contains six logic inverters which accept standard 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 greater noise
margin than conventional inverters. Each circuit contains a Schmitt
trigger followed by a Darlington level shifter and a phase splitter
driving a TTL totem-pole output. The Schmitt trigger uses positive
feedback to effectively speed-up slow input transitions, and provide
different input threshold voltages for positive-going and negative-going
input threshold (typically 800mV) is determined internally by resistor
ratios and is insensitive to temperature and supply voltage variations.

DC ELECTRICAL CHARACTERISTICS(Over recommended operating free-air temperature range unless otherwise noted.)
NOTES: For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. All typical values are at VCC = 5V, Tamb = 25°C. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, IOS tests should be performed last.
