54C89J/B

Overview

The 54C89J/B is a specialized integrated circuit manufactured by Rochester Electronics, LLC. It functions as a BCD-to-seven-segment decoder. The component is housed in a PDSO32 package and operates within standard industrial temperature ranges. As part of the 54C series, it provides digital logic decoding capabilities for display applications. The device is RoHS compliant and designed for reliable performance in electronic systems requiring segment display control.

Feature Summary

• Performs binary-coded decimal to seven-segment display decoding
• Utilizes standard plastic surface-mount packaging for board integration
• Complies with RoHS environmental standards

Applications

• Seven-segment LED display drivers
• Digital readout instrumentation
• Consumer electronic display interfaces

Procurement Notes

Verify the specific manufacturer source documentation when sourcing this component from Rochester Electronics. Confirm that the received unit matches the 54C89J/B designation and package type. Ensure compliance with project requirements regarding lead-free status and environmental certifications prior to integration into final assemblies.

Selection Notes

Select this component when a dedicated BCD-to-seven-segment decoder is required for display control. Consider the PDSO32 package dimensions for layout constraints. Evaluate compatibility with existing logic voltage levels and current drive requirements for the target display segments before implementation.

Part Context

Rochester Electronics specializes in distributing obsolete and hard-to-find components, including legacy logic families like the 54C series. The 54C89J/B represents a continuation of supply for critical decoding functions originally defined by National Semiconductor or Texas Instruments standards, ensuring availability for long-life products.

Replacement Considerations

Cross-reference with original datasheets from National Semiconductor or Texas Instruments for the 54C89 family. Verify pinout and logical function equivalence with other 54C89 variants before substitution.
