MC10H188MELG

Overview

The MC10H188MELG 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 design for stable operation
• Compatible with standard MECL 10K logic families

Applications

• High-speed digital buffering applications
• MECL logic system interconnects
• Data transmission line drivers

Procurement Notes

Verify that the specific ordering suffix matches the required package type and lead-free status. Confirm the manufacturer's current production status as legacy components may have limited availability or require alternative sourcing strategies. Ensure compatibility with existing MECL 10K infrastructure before procurement.

Selection Notes

Select this component when a hex buffer with enable functionality is required within MECL 10H systems. It serves as a functional and pinout duplication of the MECL 10K family while offering improved propagation delay characteristics without increasing power-supply current consumption.

Part Context

This device belongs to the MECL 10H series, designed for high-speed digital applications. It offers performance improvements over the standard MECL 10K family, specifically regarding propagation delay metrics, while maintaining power efficiency and logical compatibility with established MECL designs.

Replacement Considerations

The datasheet identifies the MC10H188 as a functional and pinout duplication of the standard MECL 10K family part.
