MC10H188L

Overview

The MC10H188L is a high-speed Hex Buffer with a common Enable input from the MECL 10H family. It features a functional and pinout duplication of the standard MECL 10K family part, offering a 100% improvement in propagation delay without an increase in power-supply current. The device operates within a voltage range of -5.2 V ±5%. Typical propagation delay is 1.3 ns for data-to-output transitions. Power dissipation is typically 180 mW per package under no-load conditions. The component provides improved noise margins of 150 mV over the operating voltage and temperature range.

Feature Summary

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

Applications

• High-speed digital signal buffering
• MECL logic system integration
• Data bus interface circuits

Procurement Notes

Verify the specific suffix 'L' corresponds to the CDIP-16 ceramic package when ordering. Confirm RoHS compliance requirements as standard packages may differ from Pb-free variants. Check datasheet revision history for any updates to electrical characteristics or mechanical dimensions before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring MECL 10H speed improvements while maintaining MECL 10K pinout compatibility. Ensure the design accommodates the required negative supply voltage and thermal management for typical power dissipation. Verify that the through-hole mounting method aligns with the PCB assembly capabilities.

Part Context

This device belongs to the MECL 10H series, designed for high-speed digital applications. It serves as a direct replacement for MECL 10K buffers where faster switching speeds are needed without altering the board layout. The L suffix specifically denotes the ceramic dual-in-line package suitable for robust industrial environments.
