DM74S941N

Overview

The DM74S941N is a quad buffer and line driver manufactured by onsemi, belonging to the 74S logic series. It features four non-inverting channels with complementary outputs, housed in a 20-pin Plastic Dual In-Line Package (PDIP). The device operates within a supply voltage range of 4.75V to 5.25V. It is designed for through-hole mounting and supports standard TTL input levels.

Feature Summary

• Provides four independent non-inverting buffering channels
• Generates complementary output signals for each input channel
• Compatible with standard 5V TTL logic families

Applications

• Digital signal buffering in computer systems
• Line driving for data transmission interfaces
• Logic level translation between compatible families

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability from third-party sources. Confirm package integrity upon receipt. Check manufacturing date codes as this component may be subject to end-of-life status or obsolescence notices. Ensure storage conditions comply with moisture sensitivity requirements before soldering.

Selection Notes

Select this component when a quad non-inverting buffer with complementary outputs is required in a 20-pin DIP package. It is suitable for designs utilizing the 74S bipolar logic family. Consider alternative packages if surface-mount technology is preferred. Verify that the 5V supply constraint aligns with the system power architecture.

Part Context

This part belongs to the DM74Sxx series of bipolar integrated circuits produced by onsemi. The 74S family offers higher speed performance compared to standard 74LS devices but consumes more power. The DM prefix typically denotes military or extended temperature variants, though commercial versions exist. This specific model provides robust drive capabilities for digital logic applications.

Replacement Considerations

Direct substitutes include other manufacturers' equivalents of the SN74S941 or MC74S941. Verify pin compatibility and electrical specifications such as propagation delay and output current. Ensure the replacement maintains the 20-PDIP form factor if board space is constrained.
