MC10H161MELG

Overview

The MC10H161MELG is a binary to 1-8 decoder from the MECL 10H series, manufactured by onsemi. It provides parallel decoding of a three-bit binary word to one of eight lines, with outputs going low when selected. The device operates on dual power supplies ranging from -4.94V to -5.46V and supports an operating temperature range of 0°C to +75°C. It features a typical propagation delay of 1.0 ns and power dissipation of 315 mW. The component is housed in a 16-SOEIAJ surface-mount package.

Feature Summary

• Provides true parallel decoding of a three-bit input word to eight output lines
• Designed for high-speed multiplexer and demultiplexer applications
• Eliminates unequal parallel path delay times found in other decoder designs
• Outputs go low when selected while all others remain high

Applications

• High-speed multiplexer/demultiplexer systems
• Parallel decoding circuits requiring minimal path delay
• MECL 10K compatible logic designs

Procurement Notes

Verify the specific ordering suffix 'MELG' against current manufacturer documentation to confirm package type and lead-free status. Confirm that the 16-SOEIAJ package dimensions match your PCB footprint requirements. Check for any product change notices or obsolescence announcements related to this specific part number before finalizing procurement plans.

Selection Notes

Select this component for applications requiring fast parallel decoding within the MECL 10H logic family. Ensure the design accommodates the required dual power supply voltage range and thermal management for approximately 315 mW dissipation. Verify compatibility with existing MECL 10K circuitry if used in mixed environments.

Part Context

This decoder belongs to the MC10H161 family, which includes variants in PLCC, CDIP, and PDIP packages. The 'MELG' suffix specifically denotes the SOEIAJ-16 surface mount package with lead-free construction. It serves as a core logic element for address decoding and signal routing in high-speed digital systems.

Replacement Considerations

MC10H161FN (PLCC-20), MC10H161L (CDIP-16), MC10H161P (PDIP-16). These are functionally equivalent decoders in different physical packages.
