SN74LS258BNE4

Overview

The SN74LS258BNE4 is a quadruple 2-line to 1-line data selector/multiplexer with 3-state outputs manufactured by Texas Instruments. It belongs to the LS logic series and operates within a supply voltage range of 4.75 V to 5.25 V. The device features a propagation delay of 21 ns and supports low-level output currents up to 24 mA. It is housed in a 16-pin SOIC-Narrow package designed for surface mount installation.

Feature Summary

• Provides four independent multiplexing channels for data selection
• Outputs support three-state operation for bus driving applications
• Compatible with standard TTL input logic levels

Applications

• Data routing in digital communication systems
• Address decoding circuits
• General-purpose data selection tasks

Procurement Notes

Verify the specific suffix 'E4' against official documentation to confirm compliance details, as this variant may differ from the base SN74LS258BDR or SN74LS258BD models. Ensure the procurement source provides valid RoHS certification matching the component's environmental specifications. Cross-reference the manufacturer part number directly with Texas Instruments records to avoid counterfeit components.

Selection Notes

Select this component when four independent 2-to-1 multiplexing functions are required with 3-state output control. The LS series offers standard drive capabilities suitable for general logic applications. Verify that the SOIC-Narrow package fits the PCB layout constraints and that the 21 ns propagation delay meets the system timing requirements.

Part Context

This component is part of the SN74LS258 family of multiplexers. While similar to the SN74ALS258AN which uses Advanced Low-power Schottky technology, the SN74LS258BNE4 utilizes standard Low-power Schottky logic. It shares functional similarities with other quad multiplexers but is distinct in its specific package type and electrical characteristics defined by the LS series standards.
