SN74LV541ATNSR

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 layout.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.
