CD4063BD

Comparators Overview

The CD4063BD is a 4-bit magnitude comparator from the Harris Corporation 4000/14000/40000 series. It features true active-high outputs for A<B, A=B, and A>B comparisons. The device utilizes CMOS technology in a 16-lead ceramic dual in-line package (CDIP). It operates within a supply voltage range of 5V to 15V, with a typical propagation delay of 1250 ns. The component supports cascading for multi-bit expansion and functions reliably across an industrial temperature range of -55°C to 125°C.

Comparators Feature Summary

• Provides three distinct true output states indicating less than, equal to, or greater than relationships between two 4-bit binary inputs.
• Supports cascading capability to extend comparison functionality beyond four bits using dedicated input/output pins.
• Maintains stable threshold behavior and process stability across extreme environmental temperatures.

Comparators Applications

• Digital data processing systems requiring direct binary value comparison
• Industrial control logic involving temperature or sensor value thresholds
• Cascaded arithmetic logic units for extended bit-width operations

Comparators Procurement Notes

Verify that the specific orderable part matches the CD4063BD designation, as suffixes may indicate package variations or tape-and-reel options not detailed in standard datasheets. Confirm RoHS compliance status, as historical Harris documentation indicates non-compliance for certain variants. Ensure the supplier provides traceability for the ceramic DIP package and valid lot codes for military-grade temperature specifications.

Comparators Selection Notes

Select this component when a dedicated hardware comparator is required for 4-bit binary values without external microcontroller intervention. The CDIP package is suitable for high-reliability applications requiring hermetic sealing. Consider the 1250 ns propagation delay when designing high-speed timing circuits, as this device is optimized for general-purpose logic rather than rapid switching applications.

Comparators Part Context

This device belongs to the standard 4000-series CMOS logic family, known for wide supply voltage tolerance and compatibility with various logic families. The CD4063BD specifically addresses the need for parallel data comparison in legacy and industrial systems where discrete comparator ICs are preferred over programmable solutions.

Comparators Replacement Considerations

The CD4063BF3A is a documented variant within the same series offering identical logical function but potentially different manufacturing lot qualifications. Verify pinout compatibility before substitution, as package dimensions remain consistent across the CDIP16 form factor.
