74LV17A
Hex buffer Schmitt trigger
Rev. 1 — 18 May 2017
Product data sheet
1
General description
The 74LV17A is a hex buffer 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.
