74141PC

Overview

The 74141PC is a TTL-compatible BCD-to-decimal decoder and driver manufactured by Rochester Electronics, LLC. It features a 16-pin DIP package and operates with a supply voltage range of 4.5V to 5.5V. The device accepts four binary-coded decimal inputs and activates one of ten active-low outputs corresponding to the decoded value. It is designed for driving low-current loads directly.

Feature Summary

• Decodes four-bit binary coded decimal (BCD) input into ten active-low decimal outputs
• TTL-compatible logic levels for direct interface with standard digital circuits
• Direct drive capability for low-current indicators such as neon lamps or LEDs

Applications

• Driving decimal display indicators in test equipment
• Control logic for numeric readout systems
• Decoder functions in industrial control panels

Procurement Notes

Verify the manufacturer marking on the component body to confirm it originates from Rochester Electronics, LLC, as this part may be sourced from various original manufacturers through authorized distributors. Ensure the package type matches the required 16-pin DIP specification for your PCB layout. Check for any specific lot traceability requirements if applicable to your quality standards.

Selection Notes

Select this component when a dedicated BCD-to-decimal decoding function is required without external logic gates. It is suitable for applications needing direct output driving capabilities for simple visual indicators. Consider power dissipation limits and thermal management if multiple outputs are activated simultaneously in enclosed environments.

Part Context

Rochester Electronics specializes in sourcing and distributing obsolete, discontinued, and hard-to-find electronic components. The 74141PC falls under their portfolio of legacy logic devices, providing continuity for designs that rely on classic TTL technology. This part serves as a replacement for original manufacturers who no longer produce these specific logic families.

Replacement Considerations

Compatible substitutes include the SN74141N from Texas Instruments or equivalent parts from other major logic manufacturers. Verify pin compatibility and electrical characteristics before substitution.
