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)
