74LVC2G34
Dual buffer gate
Rev. 04 — 20 July 2007
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.

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

derates linearly with 2.4 mW/K.
