SN74LS258BNS

Overview

The SN74LS258BNS is a quad 2-line to 1-line data selector/multiplexer with three-state outputs from the Texas Instruments SN74LS series. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 21 ns. The device features four independent circuits, each selecting between two inputs based on control signals. It is housed in a 16-pin DIP package and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates four independent multiplexers for parallel data routing
• Provides three-state outputs for bus-driven applications
• Compatible with standard TTL logic families

Applications

• Data routing in digital systems
• Bus-oriented memory addressing
• Signal selection in instrumentation

Procurement Notes

Verify the specific suffix 'BNS' against official Texas Instruments documentation to confirm pinout compatibility and package dimensions. Ensure the component meets required RoHS standards and check for any recent product change notices that may affect availability or specifications before finalizing procurement plans.

Selection Notes

Select this component when multiple data sources require selection onto a common bus using standard LS-TTL logic levels. Consider the three-state output capability for efficient bus management. Evaluate the 21 ns propagation delay against system timing requirements to ensure signal integrity during high-speed switching operations.

Part Context

This part belongs to the SN74LS family, known for low-power Schottky performance. It serves as a fundamental building block for digital logic designs requiring data selection. The device complements other LS-series components like decoders and buffers in complex integrated circuit architectures.

Replacement Considerations

Cross-reference with SN74LS258N for direct pin-compatible alternatives. Verify electrical characteristics match if substituting with SN74F258N or SN74ALS258AN.
