CD74HCT258 - High Speed CMOS Logic Quad 2-Input Multiplexers with Inverting 3-State Outputs

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.

• 4.5-V to 5.5-V V_CC Operation
• Wide Operating Temperature Range of –55°C to 125°C
• Balanced Propagation Delays and Transition Times
• Standard Outputs Drive Up To 10 LS-TTL Loads
• Significant Power Reduction Compared to LS-TTL Logic ICs
• Inputs Are TTL-Voltage Compatible
