CD4585BPW

Overview

The CD4585BPW is a 4-bit magnitude comparator from the Texas Instruments CD4585B series, housed in a 16-lead TSSOP package. It performs A < B, A = B, and A > B comparisons with active high outputs. Operating voltage ranges from 3 V to 18 V. Propagation delays are 60 ns at 15 V and 80 ns at 5 V. Output currents reach ±6.8 mA. The device operates between -55 °C and +125 °C.

Feature Summary

• Performs 4-bit magnitude comparison functions including less than, equal to, and greater than logic.
• Provides active high output signals for direct interface compatibility.

Applications

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

Procurement Notes

Verify the specific suffix 'BPW' confirms the TSSOP-16 plastic package variant rather than the ceramic DIP option. Confirm RoHS compliance status matches current manufacturing revisions. Ensure operating temperature range requirements align with the specified -55 °C to +125 °C industrial limits before finalizing procurement orders.

Selection Notes

Select this component when a 4-bit magnitude comparison function is required in a surface-mount design. The TSSOP-16 package offers space efficiency compared to through-hole alternatives. Verify that the 3 V to 18 V supply range suits the system power architecture and that the propagation delay characteristics meet timing constraints.

Part Context

This part belongs to the CD4585B family of digital comparators manufactured by Texas Instruments. The BPW suffix specifically denotes the 16-lead thin-shrink small-outline package (TSSOP). This distinguishes it from the CD4585BE, which utilizes a standard 16-lead PDIP plastic package, offering different footprint and thermal characteristics for PCB layout.

Replacement Considerations

CD4585BE serves as a pin-compatible alternative using a PDIP package. CD4585BM is another TSSOP variant within the same family. Verify package dimensions and lead pitch compatibility when substituting these parts in existing designs.
