SN74LS258BMEL

Overview

The SN74LS258BMEL is a quad 2-to-1 data selector/multiplexer from the LS TTL series, manufactured by Motorola. It features four independent multiplexers with inverted outputs and three-state control. The device operates within a supply voltage range of 4.75 V to 5.25 V and utilizes a 16-pin SOEIAJ package. It supports surface mount installation and functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides four independent 2-to-1 data selection channels
• Features inverted logic outputs for signal routing
• Includes three-state output control for bus isolation

Applications

• Data routing in digital logic circuits
• Signal selection in microprocessor systems
• Address decoding applications

Procurement Notes

Verify the specific manufacturer origin, as this part number has been produced by multiple vendors including Motorola and Texas Instruments. Confirm the package type matches the required 16-SOEIAJ specification. Ensure compatibility with LS TTL logic levels and check for RoHS compliance status if required by current manufacturing standards.

Selection Notes

Select this component when a quad 2-to-1 multiplexer with inverted outputs and three-state capability is required. It is suitable for designs using standard 5V TTL logic families. Consider the SOEIAJ package constraints for PCB layout. Verify that the operating temperature range meets the environmental requirements of the target application.

Part Context

This component belongs to the SN74LS258 family of multiplexers. Similar variants include the SN74LS258BDR (Texas Instruments) and SN74LS258AN (Motorola). These parts share functional similarities but may differ in packaging, such as SOIC or DIP, and specific electrical characteristics defined by their respective manufacturers.

Replacement Considerations

The SN74LS258BDR from Texas Instruments is a documented equivalent offering similar functionality in a SOIC-16 package. The SN74LS258AN from Motorola provides the same logical function in a PDIP-16 package. Verify pinout and electrical specifications before substitution.
