74LVC3G34-Q100
Triple buffer
Rev. 1 — 16 May 2013
Product data sheet
1. General description
The 74LVC3G34-Q100 provides three buffers.
The inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of
the 74LVC3G34-Q100 as a translator in a mixed 3.3 V and 5 V environment.
This device is fully specified for partial power-down applications using I
OFF
. The I
OFF
circuitry disables the output, preventing a damaging backflow current through the device
when it is powered down.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.

The minimum 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

derates linearly with 2.5 mW/K.
For VSSOP8 package: above 110
