74LVC2G126-Q100
Bus buffer/line driver; 3-state
Rev. 2 — 14 December 2016
Product data sheet
1. General description
The 74LVC2G126_Q100 is a dual non-inverting buffer/line driver with 3-state outputs. An
output enable input (pin nOE) controls each 3-state output. A LOW-level at pin nOE
causes the output to assume a high-impedance OFF-state. Schmitt trigger action at all
inputs makes the circuit highly tolerant of slower input rise and fall times.
Inputs can be driven from either 3.3 V or 5 V devices. This feature allows the use of the
74LVC2G126_Q100 as a translator in a mixed 3.3 V and 5 V environment.
It 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 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 packages: above 55
C,
the value of P
tot
derates linearly at 2.5 mW/K.
For VSSOP8 packages: above 110
C,
the value of P
tot
derates linearly at 8.0 mW/K.
