74LVC2G34
Dual buffer gate
Rev. 10 — 23 February 2018
Product data sheet
1
General description
The 74LVC2G34 provides two buffers.
Inputs can be driven from either 3.3 V or 5 V devices. These features allow the use of
these devices 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 the damaging backflow current through the
device when it is powered down.

[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] When V
CC
= 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation.
[3] For SC-88 and SC-74A packages: above 87.5 °C the value of P
tot
derates linearly with 4.0 mW/K.
For X2SON6 and XSON6 packages: above 118 °C the value of P
