SN54ABT541中文资料具有 TTL 兼容型 CMOS 输入和三态输出的军用 8 通道 4.5V 至 5.5V 缓冲器数据手册TI规格书

描述 Description

The SN54ABT541 and SN74ABT541B 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 two-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. When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, 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 SN54ABT541 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ABT541B is characterized for operation from -40°C to 85°C.
