CD74HC85MTE4

Comparators Overview

The CD74HC85MTE4 is a high-speed CMOS logic device functioning as a 4-bit magnitude comparator. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -55°C to 125°C. The component features active-high outputs and is housed in a 16-SOIC package. Key electrical characteristics include a maximum propagation delay of 33ns at a load capacitance of 50pF, with output currents specified at ±5.2mA.

Comparators Feature Summary

• Provides three distinct outputs for magnitude comparison results
• Supports cascading configurations for expanded bit-width operations
• Utilizes high-speed CMOS technology for efficient performance

Comparators Applications

• Digital data processing systems requiring magnitude evaluation
• Cascaded arithmetic logic unit implementations
• Address decoding circuits in microprocessor interfaces

Comparators Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance when sourcing. Confirm the SOIC-16 package dimensions match the design footprint requirements. Ensure the supply voltage constraints align with the target system's power rails before integration.

Comparators Selection Notes

Select this component when a 4-bit comparison function is required within a HC logic family environment. Consider the wide operating temperature range for industrial applications. Evaluate the SOIC package suitability against available board space and thermal management capabilities.

Comparators Part Context

This part belongs to Texas Instruments' CD74HC series of high-speed CMOS logic devices. The HC designation signifies compatibility with standard TTL logic levels while offering improved speed and lower power consumption compared to older HCT or standard HC variants. The MTE4 suffix denotes the surface-mount SOIC packaging and environmental compliance.

Comparators Replacement Considerations

Equivalent parts include the CD74HC85M96E4 and CD74HC85MT. Verify pinout compatibility and ensure the replacement maintains the same 16-SOIC package form factor for direct substitution.
