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

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

Description

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.

Features

  • 4.5-V to 5.5-V VCC 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
