74LVC1G125
Rev. 13 — 6 November 2017
Bus buffer/line driver; 3-state
Product data sheet
1
General description
The 74LVC1G125 provides one non-inverting buffer/line driver with 3-state output. The 3-
state output is controlled by the output enable input (OE). A HIGH-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.
