MC10H158FNR2

Overview

The MC10H158FNR2 is a quad two-input multiplexer from the MECL 10H family, packaged in a 20-lead PLCC. It features common input select logic where a high level enables inputs D00-D30 and a low level enables D01-D31. The device operates on a single supply voltage of -4.94V to -5.46V with typical power dissipation of 197 mW. Propagation delay ranges from 0.5 ns (data) to 2.9 ns (select). It provides improved noise margins of 150 mV over operating voltage and temperature ranges.

Feature Summary

• Provides four independent two-channel multiplexing functions with a common select line for simplified routing.
• Features voltage compensated design ensuring stable performance across specified operating conditions.
• Delivers significantly faster propagation delays compared to standard MECL 10K family equivalents without increasing power consumption.
• Includes enhanced noise margin capabilities to maintain signal integrity under varying voltage and temperature environments.

Applications

• High-speed data routing systems requiring fast switching between multiple input sources.
• Signal path selection in communication equipment utilizing MECL logic standards.
• Digital circuit designs necessitating low propagation delay and high noise immunity.

Procurement Notes
