SN74ABT540数据手册集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF

描述 Description

The ’ABT540 octal buffers and line drivers are ideal for driving bus lines or buffer memory address registers. The devices feature inputs and outputs on opposite sides of the package that 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 corresponding 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. The SN54ABT540 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT540 is characterized for operation from -40°C to 85°C.
