MC10H162FNG

Overview

The MC10H162FNG is a binary to 1-8 decoder manufactured by onsemi, designed for high-speed multiplexer and demultiplexer applications. It provides parallel decoding of a three-bit binary word to one of eight output lines, ensuring equal parallel path delay times. The device operates with dual power supplies ranging from -4.94 V to -5.46 V and functions within an operating temperature range of 0°C to +75°C. It features a typical propagation delay of 1.0 ns and dissipates approximately 315 mW of power. The component is housed in a 20-lead PLCC package.

Feature Summary

• Provides true parallel decoding of a three-bit input word to one of eight output lines, eliminating unequal parallel path delays found in other designs.
• Features MECL 10K compatibility and voltage compensation for improved noise margins across the operating voltage and temperature range.
• Designed for high-speed multiplexer and demultiplexer applications with low typical power dissipation.

Applications

• High-speed multiplexer/demultiplexer systems
• Parallel decoding of three-bit binary words
• MECL 10K compatible logic circuits

Procurement Notes

Verify the specific ordering suffix 'FN' corresponds to the PLCC-20 package configuration before procurement. Confirm that the Pb-free status aligns with project requirements, as indicated by the 'G' suffix availability in related part numbers. Ensure environmental compliance documentation is reviewed if RoHS standards are mandatory for the application.

Selection Notes

Select this component when equal propagation delay across all decoded outputs is critical for system timing. It is suitable for applications requiring MECL 10K compatibility and operation within standard dual-supply voltage ranges. Consider the PLCC-20 package constraints for PCB layout and thermal management during the design phase.

Part Context

The MC10H162 belongs to the 10H series of logic devices from onsemi, specifically engineered for high-speed digital applications. This series emphasizes performance characteristics such as low propagation delay and robust noise immunity, making it appropriate for complex logic decoding tasks in professional electronic systems.

Replacement Considerations

Check for the MC10H162FNR2 variant if tape and reel packaging is required instead of the rail packaging associated with the FNG suffix. Verify mechanical pinout compatibility when substituting with other 10H series decoders.

FAQ

How does the MC10H162 handle enable inputs?

When either or both enable inputs (E0/En2 and E1/En15) are high, the device forces all outputs low regardless of the state of the address inputs.

What is the typical power dissipation of the MC10H162?

The typical power dissipation is 315 mW, which is comparable to the legacy MECL 10K series.
