MC10H188P

Overview

The MC10H188P 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 offers a typical propagation delay of 1.3 ns from data to output and dissipates 180 mW per package under no-load conditions. It operates within a temperature range of 0°C to +75°C using a -5.2 V supply.

Feature Summary

• Provides high-speed signal buffering with a common enable control mechanism
• Features voltage compensated design for improved noise margins across operating ranges
• Maintains functional and pinout compatibility with the standard MECL 10K family

Applications

• High-speed digital signal routing in communication systems
• Clock distribution networks requiring buffered signals
• Data bus interfacing where enable-controlled isolation is required

Procurement Notes

Verify the specific suffix 'P' corresponds to the PDIP-16 plastic dual-in-line package before ordering. Confirm RoHS compliance requirements, as standard versions may differ from Pb-free variants. Ensure the application supports the negative voltage supply architecture inherent to the MECL logic family.

Selection Notes

Select this component for applications requiring fast switching speeds and low power dissipation compared to legacy MECL 10K parts. The common enable feature allows centralized control of multiple buffer channels. Verify that the system power supply can provide the necessary negative voltage rail for proper operation.

Part Context

This hex buffer belongs to the MECL 10H series, engineered to improve upon the standard MECL 10K family. It delivers a 100% improvement in propagation delay without increasing power-supply current consumption. The device maintains backward compatibility while offering enhanced performance characteristics for demanding high-speed digital designs.

Replacement Considerations

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