SN74F258D

Overview

The SN74F258D is a quad 2-to-1 data selector/multiplexer from the Texas Instruments 74F series, housed in a 16-pin SOIC package. It features four independent multiplexing circuits with three-state outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports propagation delays as low as 6 ns. Designed for through-hole or surface-mount applications, it functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrates four independent 2-to-1 multiplexers within a single 16-pin package
• Provides three-state outputs for effective bus line driving and isolation
• Delivers high-speed switching performance characteristic of the 74F logic family

Applications

• Data routing in digital communication systems
• Address decoding and selection in microprocessor interfaces
• Signal path switching in test and measurement equipment

Procurement Notes

Verify the specific suffix 'D' confirms the 16-pin SOIC package type during procurement. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the ordering part number matches the required package style and electrical specifications for your design.

Selection Notes

Select this component when multiple independent 2-to-1 signal paths are required in a compact surface-mount footprint. The 74F series offers faster switching speeds compared to standard TTL alternatives. Verify that the three-state output capability aligns with the system's bus architecture requirements.

Part Context

This device belongs to the Texas Instruments 74F (Fast) logic family, known for high-speed operation. It serves as a functional equivalent to other quad multiplexers but distinguishes itself through its specific F-series speed characteristics and three-state output configuration suitable for complex digital logic designs.

Replacement Considerations

Compatible substitutes include SN74LS258D and SN74ALS258D. Verify pin compatibility and ensure the replacement meets the required speed and power consumption specifications for the target application.
