MC10H188MEL

Overview

The MC10H188MEL is a high-speed Hex Buffer with Enable, part of the MECL 10H family. It operates on a negative supply voltage ranging from -4.94V to -5.46V. The device features a typical propagation delay of 1.3 ns and power dissipation of 180 mW per package under no-load conditions. It provides an improved noise margin of 150 mV over the operating voltage and temperature range. The component is housed in a 16-SOEIAJ surface-mount package.

Feature Summary

• High-speed data-to-output propagation
• Voltage compensated operation
• Compatible with MECL 10K logic standards

Applications

• Bus driving applications on cards or between cards
• MECL 10H logic circuits requiring hex buffering
• Systems utilizing common enable input control

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm that the SOEIAJ-16 package dimensions align with current PCB layout requirements. Check for available Pb-Free alternatives if environmental compliance is mandatory for the target application.

Selection Notes

Select this component when MECL 10H speed characteristics are required without increasing power-supply current compared to the standard MECL 10K family. Ensure the design supports the specified negative voltage supply range and termination requirements for optimal signal integrity.

Part Context

This device belongs to the MC10H188 series, representing a functional and pinout duplication of the standard MECL 10K family part. It offers a 100% improvement in propagation delay while maintaining similar power consumption levels, making it suitable for high-performance digital bus interfaces.

Replacement Considerations

Consult the manufacturer's documentation for direct replacements. Verify compatibility with existing MECL 10K designs if substituting older components.
