MC10H188FNG

Overview

The MC10H188FNG is a high-speed hex buffer with a common enable input, manufactured by onsemi. It operates within a supply voltage range of -4.94V to -5.46V and supports an operating temperature from 0°C to +75°C. The device features push-pull outputs and utilizes a 20-PLCC package. Electrical characteristics include a typical propagation delay of 1.3 ns from data to output and a power dissipation of 180 mW per package under no-load conditions.

Feature Summary

• Provides non-inverting buffering for six independent channels with a shared enable control
• Delivers improved noise margin of 150 mV across the full operating voltage and temperature range
• Offers functional and pinout compatibility with the standard MECL 10K family while reducing propagation delay

Applications

• High-speed digital signal buffering in MECL logic systems
• Data bus interface circuits requiring common enable functionality
• System designs transitioning between MECL 10K and 10H families

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as Pb-Free packages are available but require specific ordering suffixes. Ensure procurement specifications match the required 20-PLCC package type and verify that the device meets the necessary environmental operating ranges for the intended application.

Selection Notes

Select this component when a high-speed hex buffer with a common enable input is required. It serves as a drop-in replacement for MECL 10K buffers, offering faster propagation delays without increased power consumption. Consider the 20-PLCC package constraints and ensure the system design accommodates the specified negative supply voltage requirements for proper operation.

Part Context

This part belongs to the MECL 10H series, designed for high-speed applications. It functions as a logical successor to the MECL 10K family, providing enhanced performance metrics such as reduced propagation delay. The device maintains electrical compatibility with existing MECL designs while improving noise immunity and switching speed for demanding digital logic environments.

Replacement Considerations

The MC10H188P (PDIP-16) and MC10H188L (CDIP-16) offer alternative packaging options within the same functional family. Verify pinout compatibility and thermal management requirements when substituting these variants. Ensure the selected replacement matches the required package dimensions and lead configuration for the target PCB layout.
