SN74LVC541A-Q1 汽车类具有三态输出的八路缓冲器/驱动器
SN74LVC541A-Q1 描述
The SN74LVC541A octal buffer/driver is designed for 2.7-V to 3.6-V VCC operation.
The device is ideal for driving bus lines or buffering memory address registers.
This device features inputs and outputs on opposite sides of the package to facilitate printed circuit board layout.
The 3-state control gate is a 2-input AND gate with active-low inputs so that, if either output enable (OE1 or OE2) input is high, all eight outputs are in the high-impedance state.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment.
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.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver
