MC10H188FN

Overview

The MC10H188FN is a high-speed Hex Buffer with Enable, part of the MECL 10H family. It features a common enable input and operates within a voltage range of -4.94V to -5.46V. The device provides six non-inverting buffers in a single package. Electrical characteristics include a typical propagation delay of 1.3 ns from data to output and power dissipation of 180 mW per package under no-load conditions. It utilizes push-pull outputs and is housed in a 20-PLCC surface-mount package.

Feature Summary

• High-speed hex buffer functionality with a common enable control
• Functional and pinout compatibility with standard MECL 10K family parts
• Voltage compensated design for stable operation across operating ranges
• Improved noise margin performance over standard operating voltage and temperature

Applications

• High-speed digital signal buffering
• MECL logic system interconnects
• Data bus driving applications
• Clock distribution networks requiring enable control

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified suppliers. Confirm the specific FN suffix indicates the 20-PLCC package variant. Check RoHS compliance status as standard versions may differ from Pb-Free alternatives. Ensure environmental handling precautions are followed during storage and assembly processes.

Selection Notes

Select this component when MECL 10K compatibility is required alongside improved propagation delay specifications. Consider the common enable feature for synchronized multi-bit data routing. Evaluate thermal management requirements given the specified power dissipation levels. Verify that the 20-PLCC footprint aligns with existing PCB layout constraints.

Part Context

This device belongs to the MECL 10H series, designed to offer enhanced speed without increasing power consumption compared to the legacy MECL 10K family. The MC10H188 specifically provides hex buffering capabilities. It serves as a direct functional replacement for older MECL components while maintaining electrical compatibility.

Replacement Considerations

The MC10H188FNG is the lead-free equivalent of this component. Both variants share identical electrical characteristics and pinouts. Select the FNG suffix if lead-free manufacturing processes are mandated by project specifications.
