MC10H174L

Overview

The MC10H174L is a Dual 4-to-1 Multiplexer from the MECL 10H series, manufactured by onsemi. It features a CDIP-16 package and operates within a supply voltage range of -4.94 V to -5.46 V. The device provides a typical propagation delay of 1.5 ns with a typical power dissipation of 305 mW. It includes an enable input for output control and maintains compatibility with standard MECL 10K logic families.

Feature Summary

• Dual 4-to-1 multiplexing functionality
• MECL 10K pinout and functional compatibility
• Voltage compensated design
• Improved noise margin over operating ranges

Applications

• High-speed data routing systems
• Signal selection in communication equipment
• Logic circuits requiring differential outputs

Procurement Notes

Verify the specific ordering suffix 'L' corresponds to the ceramic dual-in-line package (CDIP-16) as defined in the datasheet. Confirm that the required lead-free status matches the 'G' suffix variant if environmental compliance is mandatory. Check current availability as this component may be subject to obsolescence notices.

Selection Notes

Select the MC10H174L when a dual 4-to-1 multiplexer with MECL 10H speed characteristics is required. Ensure the application supports the negative supply voltage requirements of the ECL family. Consider the CDIP-16 package constraints for thermal management and board space compared to surface-mount alternatives like the FN or M suffixes.

Part Context

This component belongs to the MC10H174 family of dual multiplexers. The 'L' suffix specifically denotes the ceramic DIP package variant. Other variants include plastic DIP (P), PLCC (FN), and SOEIAJ (M) packages, all sharing identical electrical performance but differing in physical form factor and mounting style.

Replacement Considerations

Direct replacements must maintain MECL 10H compatibility and dual 4-to-1 functionality. Verify pinout alignment with the CDIP-16 configuration. Cross-reference with other manufacturers offering MECL-compatible multiplexers if onsemi supply is unavailable.
