MC10H189PG

Overview

The MC10H189PG is a Hex Inverter with Enable manufactured by onsemi, housed in a 16-pin PDIP package. It operates within a supply voltage range of -4.94 V to -5.46 V and supports an operating temperature from 0°C to +75°C. The device features a typical propagation delay of 1.3 ns for data-to-output transitions and 0.7 ns for enable control. Power dissipation is typically 180 mW per package under no-load conditions.

Feature Summary

• Provides hex inverting functionality controlled by a common enable input
• Features MECL 10K compatibility with improved noise margins
• Offers voltage compensated operation across the operating range

Applications

• High-speed digital logic inversion
• MECL 10K system replacements
• Enable-controlled signal routing

Procurement Notes

Verify the specific ordering suffix 'P' confirms the Plastic Dual-In-Line (PDIP) package configuration. Confirm that the 'G' suffix indicates a lead-free compliant variant if required by assembly specifications. Ensure the procurement channel provides valid traceability documentation for this discontinued component series.

Selection Notes

Select this component when a high-speed hex inverter with a global enable function is required. It serves as a direct functional replacement for standard MECL 10K family parts while offering faster propagation delays without increasing power consumption. Verify that the differential output requirements match the application's impedance matching needs.

Part Context

This part belongs to the MECL 10H™ family, designed for high-speed applications. It functions as a pinout-compatible upgrade to the legacy MECL 10K™ series, delivering significant performance improvements in switching speed while maintaining identical power-supply current characteristics for seamless integration into existing designs.

FAQ

How does the Enable input affect the outputs?

When the Enable input is low, the hex inverting function operates normally. When the Enable input is high, all outputs are forced to a low state.

Is this device compatible with MECL 10K systems?

Yes, the MC10H189 is a functional and pinout duplication of the standard MECL 10K family part, ensuring compatibility.
