MC10161L

Overview

The MC10161L is a high-speed ECL 10K binary-to-8-line decoder manufactured by onsemi. It provides parallel decoding of a three-bit binary word to one of eight output lines, ensuring equal parallel path delay times. The device operates with a nominal negative supply voltage of -5.2 V and features ceramic DIP-16 packaging. Designed for multiplexer and demultiplexer applications, it delivers low propagation delays typical of the MECL 10K family while maintaining improved noise margins across operating conditions.

Feature Summary

• Provides true parallel decoding of three-bit binary inputs to eight output lines
• Eliminates unequal parallel path delay times found in other decoder designs
• Features improved noise margin over the full operating voltage and temperature range
• Compatible with standard MECL 10K logic families

Applications

• High-speed multiplexer systems
• Demultiplexer architectures
• Parallel decoding circuits requiring matched path delays

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified suppliers. Confirm RoHS compliance status as older ceramic packages may differ from modern standards. Ensure the specific suffix matches required lead finish and package variant. Request original manufacturer documentation to validate part history and traceability before integration into production.

Selection Notes

Select this component when equal propagation delay across all decoded outputs is critical. The ceramic DIP-16 package suits high-reliability environments where surface mount options are unsuitable. Verify that the system operates within the standard ECL -5.2 V supply requirements. Consider thermal dissipation capabilities inherent to the ceramic construction for dense circuit board layouts.

Part Context

Part of the MC10H series high-speed ECL logic family designed for demanding digital applications. The MC10161L specifically addresses the need for precise timing in parallel data routing. It complements other MECL 10K components such as gates, flip-flops, and drivers to form complete high-speed digital systems.

Replacement Considerations

MC10H161FN: Pin-compatible alternative in plastic PLCC package. MC10H161FNG: Green version of the plastic PLCC variant. Verify electrical compatibility and package dimensions before substitution.
