Quadruple 2-Line to 1-Line Data Selectors/Multiplexers With 3-State Outputs
Product details
Parameters
Package | Pins | Size
Features
- 3-State Outputs Interface Directly With System Bus
- Provide Bus Interface From Multiple Sources in High-Performance Systems
- Package Options Include Plastic Small-Outline (D) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs
Description
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.
