MC10H158P

Overview

The MC10H158P is a quad two-channel multiplexer from the MECL 10H family, featuring common input select. It operates on a single negative supply voltage ranging from -4.94 V to -5.46 V. The device provides non-inverting outputs with typical propagation delays of 1.5 ns and power dissipation of 197 mW. It utilizes a PDIP-16 package and supports an operating temperature range of 0°C to +75°C.

Feature Summary

• Provides four independent two-to-one multiplexing channels controlled by a single common select line.
• Features voltage compensated design ensuring improved noise margins across the full operating voltage and temperature range.
• Offers functional and pinout compatibility with the standard MECL 10K family while delivering significantly faster propagation delay without increasing power consumption.

Applications

• High-speed digital signal routing in telecommunications equipment
• Data acquisition systems requiring fast channel selection
• Test and measurement instrumentation logic circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as original specifications may differ from current manufacturing standards. Ensure proper handling procedures are followed for ECL logic devices during storage and assembly.

Selection Notes

Select this component when high-speed switching with low propagation delay is required within a MECL environment. Consider the PDIP-16 package constraints for through-hole mounting requirements. Evaluate thermal management needs given the specified power dissipation levels under maximum load conditions.

Part Context

Part of the MECL 10H series designed for high-performance applications. This specific model serves as a direct replacement for legacy MECL 10K multiplexers, offering enhanced speed characteristics while maintaining identical pin configurations for easy circuit board upgrades.
