Download datasheets and manufacturer documentation for Texas Instruments SN74HC257PWR1G4.

These 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 (G\) input is at a high logic level.

To ensure the high-impedance state during power up or power down, (G\) should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
