• Supports through-hole mounting via 16-pin DIP configuration

Applications

• Digital data transmission error detection
• Memory system parity verification
• Computer bus interface integrity monitoring

Procurement Notes

Verify the manufacturer designation as National Semiconductor, now part of Microchip Technology, to ensure authenticity. Confirm the package type matches the specified 16-DIP (0.300 inch) form factor. Check for lead-free and RoHS compliance status if required by your assembly process. Ensure the product status is listed as active or available for procurement from authorized distributors.

Selection Notes

Select this component when nine parallel parity channels are required within a single package. It is suitable for designs utilizing standard 5V TTL logic supplies. Consider the 16-pin DIP footprint for prototyping or legacy board replacements. Evaluate the specific output current requirements against the 16 mA low and 800 µA high specifications to ensure adequate drive capability for the load.

Part Context

This component belongs to the family of logic parity generators and checkers manufactured by National Semiconductor. These devices are essential for maintaining data accuracy in digital communication and storage applications. The 9348PC specifically offers multiple channels in a compact DIP package, distinguishing it from single-channel alternatives.

Replacement Considerations

The 9348DC is documented as a comparable variant from the same manufacturer with identical functional descriptions. Verify pinout compatibility and electrical characteristics before substitution. No other specific substitute part numbers are confirmed in the provided documentation.
