1 / 5 page CD54HCT258, CD74HCT258 QUADRUPLE 2-LINE TO 1-LINE SELECTORS/MULTIPLEXERS WITH 3-STATE OUTPUTS SCHS276A – MAY 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D 4.5-V to 5.5-V VCC Operation D Wide Operating Temperature Range of –55 °C to 125°C D Balanced Propagation Delays and Transition Times D Standard Outputs Drive Up To 10 LS-TTL Loads D Significant Power Reduction Compared to LS-TTL Logic ICs D Inputs Are TTL-Voltage Compatible description/ordering information 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 VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
