74LVC1G126
Bus buffer/line driver; 3-state
Rev. 08 — 9 April 2009
Product data sheet
1. General description
The 74LVC1G126 provides one non-inverting buffer/line driver with 3-state output. The
3-state output is controlled by the output enable input (OE). A LOW-level at pin OE causes
the output to assume a high-impedance OFF-state.
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.

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 TSSOP5 and SC-74A packages: above 87.5
°C
the value of P
tot
derates linearly with 4.0 mW/K.
For XSON6 package: above 118
