74LVC3G14
Triple inverting Schmitt trigger with 5 V tolerant input
Rev. 07 — 12 June 2008
Product data sheet
1. General description
The 74LVC3G14 provides three 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 TSSOP8 package: above 55
°C
the value of P
tot
derates linearly with 2.5 mW/K.
For VSSOP8 package: above 110
°C
the value of P

derates linearly with 8 mW/K.
For XSON8, XSON8U and XQFN8U packages: above 45
°C
the value of P
