MC10H165P

Overview

The MC10H165P is an 8-input priority encoder from the MECL 10H family, packaged in a 16-pin PDIP. It encodes eight active-high inputs into a binary-coded output representing the highest-priority input. The device features synchronous operation via a clock pin that latches outputs when high. It operates on dual power supplies ranging from -4.94V to -5.46V and supports an operating temperature range of 0°C to +75°C.

Feature Summary

• Encodes eight inputs to a binary coded output based on priority
• Synchronous operation with latch capability controlled by a clock signal
• Voltage compensated design for stable performance across operating ranges
• Compatible with standard MECL 10K logic families

Applications

• Decoding system status on a priority basis
• Peripheral controllers requiring interrupt handling
• Testing systems for checking component status
• Addressing ROMs or RAMs using random logic inputs

Procurement Notes

Verify package suffix 'P' corresponds to the 16-pin PDIP format. Confirm voltage supply requirements match the -5.2V nominal specification. Check RoHS compliance status if lead-free variants are required for assembly processes. Ensure thermal management meets the specified operating temperature limits during installation.

Selection Notes

Select this component when high-speed encoding of multiple signals is necessary within a MECL environment. Consider the PDIP package for through-hole prototyping or specific board layouts. Evaluate propagation delay specifications against system timing requirements. Verify compatibility with existing MECL 10K infrastructure for seamless integration.

Part Context

Part of the MECL 10H series offering improved propagation delays over the older MECL 10K family without increasing power consumption. Designed for applications requiring fast, reliable encoding of digital signals in high-performance computing and communication systems.

Replacement Considerations

MC10H165L (CDIP-16) offers identical functionality in a ceramic package. MC10H165FN (PLCC-20) provides surface mount options. Verify pinout compatibility and thermal characteristics when substituting packages.
