SN74S258N

Signal Switches, Multiplexers, Decoders Overview

The SN74S258N is a quadruple 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports a commercial operating temperature range from 0 °C to +70 °C. The device features a propagation delay of 9 ns and utilizes TTL input types with non-inverting and inverting outputs. It is housed in a 16-pin PDIP package designed for through-hole mounting.

Signal Switches, Multiplexers, Decoders Feature Summary

• Integrates four independent multiplexers, each selecting between two data inputs based on a common select line.
• Provides both non-inverting (Y) and inverting (W) output signals simultaneously for each channel.
• Features three-state outputs controlled by an enable input to facilitate bus-oriented connections.

• Data routing in digital logic systems
• Bus-oriented transmission networks
• Digital signal selection circuits

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm active production status and lead finish specifications. Ensure the selected variant matches the required packaging format and environmental compliance standards for your assembly process.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when high-speed switching is required due to its S-series propagation characteristics. Confirm that the system power supply remains strictly within the specified 4.75 V to 5.25 V limits to ensure reliable operation and prevent electrical overstress.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN54/74S series of logic devices, which are characterized by Schottky-clamped transistor-transistor logic technology. This family provides faster switching speeds compared to standard or low-power variants while maintaining compatibility with existing TTL logic levels.
