7430DC

Overview

The National Semiconductor 7430DC is a single NAND gate integrated circuit belonging to the standard TTL logic family. It features a 14-pin Ceramic Dual In-Line Package (CDIP) configuration. The device performs the logical NAND function, providing one channel of processing within a single package. It is designed for digital logic applications requiring reliable signal inversion and combination.

Feature Summary

• Single-channel NAND logic gate implementation
• TTL technology construction
• Ceramic dual in-line packaging

Applications

• Digital logic circuits
• Signal processing systems
• Computer peripheral interfaces

Procurement Notes

Verify the specific manufacturer origin, as National Semiconductor assets are now managed by Texas Instruments. Confirm the package material is ceramic CDIP rather than plastic variants. Ensure the component meets required environmental standards if applicable to the end application.

Selection Notes

Select this component when a robust, single NAND gate is required in a high-reliability environment suitable for ceramic packaging. Consider thermal management requirements associated with through-hole mounting. Verify compatibility with existing TTL voltage levels and logic thresholds in the target system design.

Part Context

This part belongs to the 7400 series of logic ICs, a foundational standard in digital electronics. The 7430 specifically provides an 8-input NAND gate function, though packaged as a single functional unit. It represents legacy technology still used in maintenance or specialized industrial control systems.

Replacement Considerations

Direct substitutes include the DM7430 from National Semiconductor/Texas Instruments. Alternative manufacturers may offer equivalent logic functions in different packages, such as SOIC or DIP-14 plastic versions, provided pinouts remain compatible.
