SN74F258N

Overview

The SN74F258N is a quad 2-to-1 data selector/multiplexer with three-state outputs from the Texas Instruments SN74F series. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 6 ns. The device supports four independent circuits, each selecting between two inputs based on control signals. It is housed in a 16-pin PDIP package designed for through-hole mounting. The component functions reliably across an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides four independent channels for routing one of two input lines to a single output
• Integrates three-state output capability to facilitate bus-oriented systems
• Utilizes Schottky diode logic technology for high-speed switching performance

Applications

• Data selection and multiplexing in digital logic circuits
• Bus-oriented system architectures requiring signal routing
• Industrial control applications involving data path management

Procurement Notes

Verify that the specific part number matches the required logic family and package type. Confirm RoHS compliance status as indicated in official documentation. Ensure the procurement source provides valid manufacturer traceability. Check for any specific ordering suffixes that may alter electrical characteristics or packaging format before finalizing orders.

Selection Notes

Select this component when four independent 2-to-1 multiplexing functions are required with three-state output control. The SN74F series offers faster switching speeds compared to standard TTL alternatives. Consider the PDIP-16 package constraints for through-hole assembly processes. Evaluate the 6 ns propagation delay against system timing requirements to ensure adequate performance margins.

Part Context

This device belongs to the SN74F logic family, characterized by Schottky diode technology for improved speed. It serves as a data selector within the broader category of encoders, decoders, and multiplexers. The SN74F258N provides a parallel solution for managing multiple data paths in complex digital designs.

Replacement Considerations

The SN74LS258BD is a documented alternative offering similar functionality in a surface-mount SOIC package. Verify pin compatibility and electrical specifications when substituting components.
