MC10H188M

Overview

The MC10H188M is a high-speed Hex Buffer with Enable, part of the MECL 10H family. It features one element with six bits per element and push-pull outputs in a 16-SOEIAJ package. Operating voltage ranges from -4.94V to -5.46V. Propagation delay is typically 1.3 ns data-to-output. Power dissipation is 180 mW typical at no load. The device operates within a temperature range of 0°C to +75°C.

Feature Summary

• High-speed hex buffer functionality with common enable input
• Functional and pinout duplication of standard MECL 10K family parts
• Voltage compensated design for stable operation
• Improved noise margin over operating voltage and temperature range

Applications

• High-speed digital signal buffering
• MECL logic system interfacing
• Data transmission line termination

Procurement Notes

Verify RoHS compliance status as the base model may not be compliant; check for 'G' suffix variants for lead-free options. Confirm package type matches SOEIAJ-16 requirements. Ensure supply chain sources provide official datasheets matching publication number MC10H188/D. Validate that procurement channels are authorized distributors to guarantee component authenticity and storage history integrity.

Selection Notes

Select this component when MECL 10K compatibility is required alongside improved propagation delay characteristics. Consider the 16-SOEIAJ package for surface-mount applications requiring compact footprints. Evaluate power dissipation limits against thermal management capabilities. Verify that the enable logic polarity (active low) aligns with system control signals before integration into the design architecture.

Part Context

This device belongs to the MECL 10H series, designed to offer performance enhancements over the legacy MECL 10K family without increasing power consumption. It serves as a direct functional replacement for specific 10K buffers while providing faster switching speeds. The series maintains industry-standard pinouts to facilitate easier migration for existing designs upgrading to higher speed requirements.

Replacement Considerations

MC10H188P (PDIP-16), MC10H188L (CDIP-16), MC10H188FN (PLCC-20). These variants share identical electrical specifications and pinouts but differ in physical packaging.
