MC10H188MG

Overview

The MC10H188MG is a high-speed Hex Buffer with Enable manufactured by onsemi. It operates within a supply voltage range of -4.94 V to -5.46 V and features a typical propagation delay of 1.3 ns from data to output. The device dissipates approximately 180 mW per package under no-load conditions. It utilizes an SOEIAJ-16 surface-mount package and supports an operating temperature range from 0°C to +75°C.

Feature Summary

• Provides hex buffering functionality with a common enable input for signal control
• Delivers improved noise margin across the full operating voltage and temperature range
• Maintains compatibility with MECL 10K logic standards while offering faster propagation delays

Applications

• High-speed digital signal buffering in communication systems
• Data bus driving applications requiring controlled enable states
• MECL logic interface circuits demanding low propagation delay

Procurement Notes

Verify the specific ordering suffix to confirm the package type, as the MG suffix denotes the SOEIAJ-16 variant. Confirm RoHS compliance status if required for your assembly process, noting that Pb-free options are available within the product family. Ensure the design accommodates the specified negative supply voltage requirements for proper operation.

Selection Notes

Select this component when a hex buffer with a shared enable control is required for MECL 10H applications. It serves as a functional replacement for standard MECL 10K buffers with enhanced speed characteristics. Consider the SOEIAJ-16 package constraints and thermal dissipation capabilities during the PCB layout phase to ensure reliable performance.

Part Context

This part belongs to the MECL 10H series, designed for high-speed digital applications. It functions as a pinout-compatible upgrade to the MECL 10K family, providing significant improvements in propagation delay without increasing power consumption. The series is widely used in telecommunications and high-performance computing environments.

FAQ

How does the Enable input affect the outputs?

When the Enable input is in the high state, all outputs are forced to the low state. When the Enable input is low, the outputs follow the logic state of the inputs.

Is this device compatible with MECL 10K logic?

Yes, the MC10H188 is functionally and pinout compatible with the standard MECL 10K family parts, allowing for direct upgrades with improved speed.
