DESCRIPTION/ORDERING INFORMATION  
The SN74LVC257A-EP quadruple 2-line to 1-line data selector/multiplexer is designed for 2.7-V to 3.6-V VCC  
operation.  
The device is designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized  
systems. The 3-state outputs do not load the data lines when the output-enable (OE) input is at a high logic  
level.  
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator 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 VCC through a pullup  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
