DESCRIPTION

SF00028

The 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.

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 V = 5V, T = 25°C.

amb

Not more than one output should be shorted at a time. For testing I , 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, I tests should be performed last.
