Automotive Catalog Quadruple 2-Line To 1-Line Data Selector/Multiplexer With 3-State Outputs

The SN74LVC257A 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.
