74LVC541A
Rev. 5 — 13 March 2020
Octal buffer/line driver with 5 V tolerant inputs/outputs;
3-state
Product data sheet
1. General description
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 I
OFF
. The I
OFF
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.
2. Features and benefits
