SN74LV541AT 具有三态输出的八路缓冲器/驱动器
SN74LV541AT 描述
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
