SN74LVC540A octal buffer/driver is designed for

These devices are ideal for driving bus lines or  
buffer memory address registers. These devices  
featureinputsandoutputsonoppositesidesofthe  
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 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 these devices as translators  
in a mixed 3.3-V/5-V system environment.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
The SN54LVC540A is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74LVC540A is characterized for operation from –40°C to 85°C.
