54141DM

Overview

The 54141DM is a TTL-compatible BCD-to-decimal decoder/driver manufactured by Rochester Electronics. It accepts four-bit binary-coded decimal inputs and activates one of ten active-low outputs corresponding to the decimal value. The device operates within a standard temperature range and utilizes a ceramic dual in-line package for robust environmental stability.

Feature Summary

• Converts four-bit binary-coded decimal input signals into ten distinct active-low output lines
• Provides direct drive capability for common-cathode display applications
• Features high noise immunity suitable for industrial digital logic environments

Applications

• Driving ten-segment displays in industrial control panels
• Address decoding in legacy computer memory systems
• Digital indicator circuits requiring decimal representation

Procurement Notes

Verify component authenticity through manufacturer documentation, as Rochester Electronics supplies reclaimed or surplus inventory. Confirm lot traceability and physical condition prior to integration. Ensure compatibility with existing system voltage levels and thermal requirements during procurement planning.

Selection Notes

Select this component when designing systems requiring reliable BCD-to-decimal conversion using established TTL logic standards. Consider the ceramic package for enhanced durability in harsh operating conditions compared to plastic alternatives.

Part Context

Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find semiconductor components. This part represents a continuation of availability for legacy integrated circuits no longer produced by original equipment manufacturers.

Replacement Considerations

Direct functional equivalents include the SN54141J and MC54141J. Verify pinout compatibility and electrical specifications before substitution.
