SN74F258DG4

Overview

The SN74F258DG4 is a quad 2-to-1 data selector/multiplexer from the Texas Instruments SN74F series, housed in a 16-pin SOIC package. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device supports a propagation delay of 6 ns 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 high-impedance three-state outputs for bus driving
• Utilizes FAST TTL logic technology for rapid switching speeds

Applications

• Data routing in digital communication systems
• Address decoding circuits
• Signal selection in microprocessor interfaces

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free composition and RoHS compliance when sourcing. Confirm the SOIC package type matches your PCB footprint requirements. Ensure the manufacturer is Texas Instruments to guarantee original component authenticity and performance specifications.

Selection Notes

Select this component for applications requiring multiple independent signal paths with controlled output states. The SN74F series offers faster switching than standard 74LS counterparts. Verify that the 16-pin surface mount package fits the assembly constraints and that the 5V logic levels align with the system design.

Part Context

This part belongs to the SN74F family of high-speed TTL logic devices. It serves as a functional equivalent to other quad multiplexers but distinguishes itself through its specific three-state output configuration and surface-mount packaging. It is designed for general-purpose digital logic applications requiring reliable signal selection.

Replacement Considerations

Compatible alternatives include the SN74F258D and SN74F258DR. These variants share identical logical functionality and pinout configurations. Verify that any substitute maintains the same three-state output capability and package dimensions for direct board replacement.
