74LVC1G126
Rev. 14 — 15 March 2019
Bus buffer/line driver; 3-state
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.
