DM74S241N

Overview

The DM74S241N is an octal buffer and line driver manufactured by Fairchild Semiconductor, belonging to the Schottky (S) logic family. It features eight non-inverting buffers with three-state outputs designed for high-speed digital applications. The device operates on a nominal 5V supply and utilizes a 20-pin plastic dual in-line package (PDIP). Key electrical characteristics include a typical propagation delay of 18 ns and output drive capabilities suitable for bus-oriented systems.

Feature Summary

• Provides eight non-inverting buffer channels with three-state output control
• Utilizes Schottky technology for improved switching speed and reduced power dissipation
• Designed for direct driving of bus lines and terminated transmission lines

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitters and receivers

Procurement Notes

Verify the manufacturer marking matches Fairchild Semiconductor or its authorized successors. Confirm the package type is PDIP-20 and the suffix indicates the standard plastic DIP variant. Ensure the component meets the required Schottky TTL specifications for voltage and current ratings before integration into the design.

Selection Notes

Select this component when high-speed buffering with three-state isolation is required in 5V logic systems. It serves as a robust interface between microprocessors and memory or peripheral buses. Consider thermal management due to Schottky power characteristics and ensure input noise margins are sufficient for the specific application environment.

Part Context

This part belongs to the 74Sxx series of high-speed Schottky TTL logic devices. It is functionally related to other octal buffers like the 74LS241 but offers faster switching speeds at the cost of higher power consumption. It is commonly used in legacy and industrial systems requiring reliable bus interfacing.

Replacement Considerations

The DM74LS241N is a pin-compatible alternative offering lower power consumption but slower performance. For equivalent Schottky speed, verify availability of other 74S241 variants from different manufacturers ensuring identical pinout and electrical characteristics.
