SN54BCT541中文资料具有三态输出的八路缓冲器/驱动器数据手册TI规格书

描述 Description

The SN54BCT541 and SN74BCT541A octal buffers and line drivers are ideal for driving bus lines or buffering memory-address registers. The devices feature 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.
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.
