The 74ACT11257 is designed to multiplex signals from 4-bit data sources to four output data lines in bus-organized systems. The 3-state outputs do not load the data lines when the output-enable input is at a high logic level.

The 74ACT11257 is characterized for operation from -40°C to 85°C.

 

 

  • Inputs Are TTL-Voltage Compatible
  • 3-State Outputs Interface Directly With System Bus
  • Flow-Through Architecture Optimizes PCB Layout
  • Center-Pin VCC and GND Configurations Minimize High-Speed Switching Noise
  • EPICTM (Enhanced-Performance Implanted CMOS) 1-m Process
  • 500-mA Typical Latch-Up Immunity at 125°C
  • Provides Bus Interface From Multiple Sources in High-Performance Systems
  • Package Options Include Plastic Small-Outline (DW) and Shrink Small-Outline (DB) Packages, and Standard Plastic 300-mil DIPs (N)
