CD4585BPWE4

Comparators Overview

The CD4585BPWE4 is a CMOS 4-bit magnitude comparator from the Texas Instruments 4000B series, housed in a 16-lead TSSOP package. It performs logical comparisons between two 4-bit binary words to determine if input A is less than, equal to, or greater than input B. The device features active-high outputs and operates within a supply voltage range of 3 V to 18 V. It supports an operating temperature range from -55 °C to +125 °C. Key electrical parameters include a maximum propagation delay of 60 ns at 15 V and a maximum power supply current of 100 µA.

Comparators Feature Summary

• Performs 4-bit magnitude comparison with active-high logic outputs
• Operates across a wide industrial temperature range
• Compatible with standard CMOS logic families

Comparators Applications

• Digital arithmetic logic units
• Address decoding systems
• Data sorting circuits

Comparators Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the TSSOP-16 package dimensions match your PCB footprint requirements. Ensure the operating environment stays within the specified -55 °C to +125 °C range for reliable performance. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Comparators Selection Notes

Select this component when a 4-bit magnitude comparison function is required in a space-constrained design utilizing surface-mount technology. The TSSOP package offers a smaller footprint compared to traditional DIP options. Consider the propagation delay characteristics relative to your system clock speed. Verify that the input voltage levels are compatible with your logic family standards.

Comparators Part Context

This part belongs to the CD4585B family of 4-bit magnitude comparators. The 'BPWE4' designation specifically identifies the plastic TSSOP package variant with environmental compliance features. It serves as a digital logic solution for comparing binary values without requiring external components for basic operations.

Comparators Replacement Considerations

The CD4585BE is a PDIP equivalent offering through-hole mounting. The CD4585BPW is a non-compliant TSSOP variant. Verify pinout compatibility before substituting.
