CD4063BE

Comparators Overview

The CD4063BE is a 4-bit magnitude comparator from the 4000/14000/40000 series, manufactured by Harris Corporation. It features true outputs and operates on CMOS technology within a 16-pin PDIP package. The device supports a supply voltage range of 5V to 15V and exhibits a propagation delay of 1250 ns. It functions across an extended temperature range from -55°C to 125°C.

Comparators Feature Summary

• Provides true output signals for direct logic interfacing without inversion requirements.
• Supports cascading capabilities for expanding comparison resolution beyond four bits.

Comparators Applications

• Digital data comparison circuits
• Address decoding systems
• Logic testing and verification

Comparators Procurement Notes

Verify component authenticity due to potential variations between original Harris Semiconductor and subsequent manufacturers like Texas Instruments Rochester Electronics. Confirm package integrity and pin configuration match the specified 16-pin DIP format. Check for RoHS compliance status as historical records indicate non-compliance for certain batches.

Comparators Selection Notes

Select this component when a dedicated 4-bit magnitude comparison function is required with true output polarity. Ensure the application environment accommodates the specified operating temperature range and supply voltage constraints. Consider the propagation delay characteristics for timing-sensitive digital designs.

Comparators Part Context

This part belongs to the standard 4000-series CMOS logic family, widely used in industrial and commercial digital systems. Harris Corporation was a primary manufacturer before Texas Instruments acquired its semiconductor assets. The CD4063BE serves as a fundamental building block for arithmetic logic units and control systems.
