74LVC3G34
Triple buffer
Rev. 13 — 26 October 2018
Product data sheet
1. General description
The 74LVC3G34 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 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.

The minimum input and output voltage ratings may be exceeded if the input and output current ratings are observed.
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
tot
derates linearly with 8 mW/K.
For XSON8, XQFN8 packages: above 118 °C the value of P
tot
derates linearly with 7.8 mW/K.
