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. Mixed 5 V and 3.3 V applications
Improved current drive and voltage level of signals
Improved signal integrity for complex layouts
Wide supply voltage range
Low propagation delay
