CD4063BF3A

Comparators Overview

The CD4063BF3A is a CMOS 4-bit magnitude comparator from the 4000/14000/40000 series, manufactured by Texas Instruments. It operates within a supply voltage range of 5 V to 15 V and features true outputs. The device is housed in a 16-lead hermetic dual-in-line ceramic package (CDIP16). Key electrical specifications include a maximum propagation delay of 1250 ns and an operating temperature range spanning from -55 °C to +125 °C.

Comparators Feature Summary

• Provides four-bit magnitude comparison with true output polarity
• Capable of cascading for multi-bit expansion
• Operates across extended industrial temperature ranges

Comparators Applications

• Digital data processing systems requiring magnitude evaluation
• Industrial control logic circuits
• Military-grade electronic instrumentation

Comparators Procurement Notes

Verify that the component matches the specific F3A suffix, which denotes the 16-lead hermetic dual-in-line ceramic package. Confirm compliance requirements as the datasheet indicates the part is not RoHS compliant. Ensure the supplier provides documentation verifying the manufacturer origin and lot traceability for this military-grade ceramic variant.

Comparators Selection Notes

Select this component when a hermetically sealed ceramic package is required for high-reliability applications. The 4000-series CMOS technology ensures compatibility with standard logic families while offering wide voltage operation. Consider the propagation delay characteristics against system timing requirements before finalizing the design integration.

Comparators Part Context

This part belongs to the CD4063B family of 4-bit magnitude comparators. While other variants exist in plastic packages or with different suffixes, the BF3A designation specifically identifies the hermetic ceramic construction. This distinguishes it from commercial grade equivalents intended for less demanding environmental conditions.

Comparators Replacement Considerations

Direct substitutes include other CD4063B variants with compatible pinouts, such as the CD4063BF. Verify package dimensions and thermal characteristics when replacing ceramic units with plastic alternatives.
