QUADRUPLE 2 LINE TO 1 LINE DATA SELECTORS/ MULTIPLEXERS WITH 3 STATE OUTPUTS

These quadruple 2-line to 1-line data selectors/ multiplexers SN54LVC257A SN74LVC257A are designed for 1.65-V to 3.6-V VCC operation. The LVC257A devices are 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 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 VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
