74LV14A
Hex inverting Schmitt trigger
Rev. 3 — 2 November 2016
Product data sheet
1. General description
The 74LV14A is a hex inverter with Schmitt-trigger inputs, capable of transforming slowly
changing input signals into sharply defined, jitter-free output signals.
Inputs are overvoltage tolerant. This feature allows the use of these devices as translators
in mixed voltage environments.
This device is fully specified for partial power down applications using I
OFF
. The I
OFF
circuitry disables the output, preventing the potentially damaging backflow current through
the device when it is powered down.

If the input current ratings are observed, the minimum input voltage ratings may be exceeded.
If the output current ratings are observed, the output voltage ratings may be exceeded.
This value is limited to 7 V maximum.
For TSSOP14 packages: above 75
C,
the value of P
tot
derates linearly at 7 mW/K.
