74LVC541ABQ: Octal buffer/line driver with 5 V tolerant inputs/outputs; 3-state

The 74LVC541A is an octal non-inverting buffer/line driver with 5 V tolerant inputs and outputs. The 3-state outputs are controlled by the output enable inputs OE1 and OE2.

This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.

Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices as translators in mixed 3.3 V and 5 V applications.
