The SN74LV541AT is designed for 4.5-V to 5.5-V VCC operation. The
inputs are TTL-voltage compatible, which allows them to be interfaced with bipolar outputs and
3.3-V devices. The device also can be used to translate from 3.3 V to 5 V.
This device is ideal for driving bus lines or buffer memory address registers. It
features inputs and outputs on opposite sides of the package to facilitate printed circuit board
The 3-state control gate is a two-input AND gate with active-low inputs so that, if
either output-enable (OE1 or OE2) input is high, all
corresponding outputs are in the high-impedance state. The outputs provide noninverted data when
they are not in the high-impedance state.
To ensure the high-impedance state during power up or power down,
OE shall be tied to VCC through a pullup resistor; the minimum value of the
resistor is determined by the current-sinking capability of the driver.
This device is fully specified for partial-power-down applications using
Ioff. The Ioff circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
