74LVC2G14
Dual inverting Schmitt trigger with 5 V tolerant input
Rev. 04 — 4 September 2007
Product data sheet
1. General description
The 74LVC2G14 provides two inverting buffers with Schmitt-trigger action.
The inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of
this device in a mixed 3.3 V and 5 V environment. Schmitt-trigger action at the inputs
makes the circuit tolerant of slower input rise and fall time. This device is fully specified for
partial power-down applications using I
OFF
. The I
OFF
circuitry disables the output,
preventing the damaging backflow current through the device when it is powered down.

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
When V
CC
= 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
For SC-88 and SC-74A packages: above 87.5
°C
the value of P
tot
derates linearly with 4.0 mW/K.
For XSON6 packages: above 45
°C
the value of P
