74LVC1G34-Q100
Single buffer
Rev. 1 — 1 October 2012
Product data sheet
1. General description
The 74LVC1G34-Q100 provides a low-power, low-voltage single buffer.
The input 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.
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.
Schmitt trigger action at all inputs makes the circuit highly tolerant of slower input rise and
fall times.
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 TSSOP5 and SC-74A packages: above 87.5
C
the value of P
tot
derates linearly with 4.0 mW/K.
