SN74AS257NSR Product Details
These data selectors/multiplexers 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 () input is at a high logic level.
The SN54ALS257A and SN54ALS258A are characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS257A, SN74ALS258A, SN74AS257, and SN74AS258 are characterized for operation from 0°C to 70°C.
- 3-State Outputs Interface Directly With System Bus
- Provide Bus Interface From Multiple Sources inHigh-Performance Systems
- Package Options Include Plastic Small-Outline (D) Packages,Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic(J) 300-mil DIPs
