MC10H159PG

Overview

The MC10H159PG is a quad 2-input multiplexer with enable, belonging to the MECL 10H series. It features inverted outputs and operates within a supply voltage range of -4.94 V to -5.46 V. The device provides a typical propagation delay of 1.5 ns and dissipates approximately 218 mW of power. It utilizes a PDIP-16 package and supports an operating temperature range from 0°C to +75°C.

Feature Summary

• Offers functional and pinout compatibility with the standard MECL 10K family while delivering improved propagation delay performance without increasing power-supply current consumption.
• Incorporates common enable and common data select inputs to control four independent multiplexing channels simultaneously.
• Provides enhanced noise margin stability across the full operating voltage and temperature range.

Applications

• High-speed digital signal routing in communication systems
• Data selection circuits requiring differential ECL logic levels
• Multiplexing applications utilizing MECL 10K compatible architectures

Procurement Notes

Verify that the specific procurement order explicitly includes the 'P' suffix to ensure the correct Plastic Dual-In-Line Package (PDIP) variant is supplied. Confirm that the component meets RoHS compliance requirements if lead-free specifications are mandatory for the assembly process. Ensure the ordering documentation accurately reflects the manufacturer's part number designation to avoid receiving alternative package styles such as CDIP or SOEIAJ.

Selection Notes

Select this component when a quad 2-input multiplexer with inverted outputs is required within a MECL 10H environment. It serves as a direct replacement for MECL 10K equivalents where faster switching speeds are necessary. Verify that the system design accommodates the negative supply voltage requirements and differential output characteristics inherent to the MECL logic family.

Part Context

This device is part of the MECL 10H series, which represents an evolution of the legacy MECL 10K logic family. The 10H series maintains backward compatibility in terms of pinouts and functionality while providing significant improvements in switching speed. This specific model integrates four independent multiplexers into a single integrated circuit package.

FAQ

How does the MC10H159PG differ from the MECL 10K family?

It offers a 100% improvement in propagation delay compared to the standard MECL 10K family while maintaining identical pinouts and not increasing power-supply current.

What is the function of the ENABLE input?

The ENABLE input controls the state of all four multiplexers simultaneously, determining whether the selected data inputs are passed to the outputs.
