Overview
The SN74ALS258ADR is a quad 2-to-1 data selector/multiplexer in a 16-pin SOIC package. It multiplexes signals from four-bit data sources to four-output data lines in bus-organized systems. The device features three-state outputs that do not load data lines when the output-enable (OE) input is at a high logic level. It operates on a single power supply ranging from 4.5V to 5.5V and is characterized for operation over an industrial temperature range of 0°C to 70°C.
Feature Summary
- Provides bus interface capability from multiple sources in high-performance systems
- Features three-state outputs to prevent loading of data lines during disabled states
- Designed specifically for multiplexing signals between 4-bit data sources and 4-output data lines
Applications
- Bus-organized system signal routing
- High-performance system data selection
- Multiplexing 4-bit data sources to output lines
Procurement Notes
Verify the specific ordering suffix 'ADR' corresponds to the SOIC tape-and-reel packaging configuration. Confirm the component status as active production within the manufacturer's current catalog. Ensure compatibility with standard surface-mount assembly processes for the specified package type.
Selection Notes
Select this component for applications requiring quad 2-to-1 multiplexing with three-state outputs. It is suitable for systems needing to interface multiple data sources onto shared buses without electrical loading. Consider the ALS series characteristics for appropriate speed and power consumption balance.
Part Context
This part belongs to the Texas Instruments SN74ALS258A family, which includes variants such as SN74ALS258AN and SN74ALS258AD. These devices are designed for use in bus-organized systems where efficient signal routing from multiple sources is required. The family supports both plastic DIP and small-outline packages.
Replacement Considerations
SN74ALS258AD is a tube-packaged equivalent. SN74ALS258AN is a PDIP alternative. SN74AS258 offers faster switching speeds but requires verification of pinout and electrical compatibility.
