SN74F258DRE4

Overview

The SN74F258DRE4 is a quad 2-to-1 data selector/multiplexer from the Texas Instruments SN74F series. It features four independent multiplexers with three-state outputs, housed in a 16-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 6 ns. It is designed for through-hole or surface-mount applications depending on the specific variant suffix, with an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates four independent 2-to-1 data selectors within a single integrated circuit
• Provides three-state outputs for bus-oriented communication and signal isolation
• Utilizes FAST TTL logic technology for high-speed switching performance

Applications

• Data routing in digital systems requiring multiple input selection
• Bus structure implementations where signal isolation is necessary
• Address decoding circuits utilizing selector functionality

Procurement Notes

Verify that the 'DRE4' suffix corresponds to the correct SOIC package and tape-and-reel packaging format. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the ordering part number matches the required pin configuration and output drive characteristics specified in the official datasheet.

Selection Notes

Select this component when four independent multiplexing channels with three-state control are required. Compare against the SN74F258N for DIP packaging alternatives if surface mount is not feasible. Consider the SN74F257DR if non-inverting outputs are preferred over the standard configuration. Verify voltage levels match the system logic requirements.

Part Context

This component belongs to the SN74F family of high-speed TTL logic devices. It serves as a functional equivalent to other industry-standard quad multiplexers but offers specific Texas Instruments manufacturing tolerances and reliability standards. The device is widely used in legacy and modern digital designs requiring reliable data path selection.

Replacement Considerations

Public confirmed substitute part numbers include SN74F258N, SN74F258NSR, SN74F258NE4, and SN74F258NSRG4. These variants share identical logical functions but differ in package type (PDIP vs SOIC) and reel specifications.
