SN74LV540A 具有三态输出的八路缓冲器/驱动器

SN74LV540A 描述

The ’LV540A devices are octal buffers/drivers designed for 2-V to 5.5-V VCC operation.

These devices are ideal for driving bus lines or buffer memory address registers. They feature 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 inverted data when they are not in the high-impedance state.

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
