MC10H188FNR2G

Overview

The MC10H188FNR2G is a high-speed Hex Buffer with Enable, part of the MECL 10H family. It features a common enable input that forces outputs low when active-high and passes inputs to outputs when active-low. The device operates on a -4.94 V to -5.46 V supply. Electrical characteristics at -5.2 V include a typical propagation delay of 1.3 ns (data-to-output) and 0.7 ns (enable-to-output). Power dissipation is typically 180 mW per package under no-load conditions.

Feature Summary

• High-speed hex buffer functionality with a single common enable control line
• Functional and pinout compatibility with standard MECL 10K family parts
• Voltage compensated design ensuring stable operation across operating ranges
• Improved noise margin of 150 mV over the full voltage and temperature range

Applications

• High-speed digital signal buffering in telecommunications equipment
• Data bus interface circuits requiring fast propagation delays
• MECL logic system replacements for legacy 10K components
• Enable-controlled output drivers for multiplexed data lines

Procurement Notes

Verify component authenticity through authorized channels. Confirm RoHS compliance status as indicated by the 'G' suffix in the ordering information. Ensure proper handling procedures are followed due to moisture sensitivity. Review the manufacturer's soldering reference manual for mounting techniques. Validate electrical specifications against specific application requirements before integration.

Selection Notes

Select this component for applications requiring MECL 10H speed improvements over 10K standards without increased power consumption. The PLCC-20 package suits surface-mount designs needing robust lead frames. Consider the enable feature for managing output states in complex logic systems. Verify thermal equilibrium conditions during testing to ensure accurate parameter measurement.

Part Context

This device belongs to the MECL 10H series, designed to offer faster propagation delays compared to the traditional MECL 10K family while maintaining identical power-supply current levels. It serves as a direct functional and pinout replacement for legacy 10K buffers, facilitating upgrades in existing high-speed digital circuit designs without requiring major layout modifications.

Replacement Considerations

The datasheet identifies the MC10H188 as a functional duplication of the standard MECL 10K family part. Specific substitute part numbers are not explicitly listed in the provided documentation.
