CD4585BPWR

Comparators Overview

The CD4585BPWR is a CMOS 4-bit magnitude comparator from the Texas Instruments CD4585B series, housed in a 16-pin TSSOP surface-mount package. It performs A < B, A = B, and A > B comparisons with active-high outputs. Operating voltage ranges from 3 V to 18 V, with a maximum supply current of 100 µA. Propagation delays are 60 ns at 15 V and 80 ns at 5 V (50 pF load). Output currents are ±6.8 mA. The device operates between -55 °C and +125 °C.

Comparators Feature Summary

Comparators Procurement Notes

Verify the specific suffix 'BPWR' confirms the 16-TSSOP plastic package and tape-and-reel orientation. Confirm the revision level matches design requirements. Ensure ESD handling protocols are followed during assembly. Validate that the operating voltage range aligns with system power rails. Check for any specific environmental compliance certifications required by the end application.

Comparators Selection Notes

Select this component when a 4-bit magnitude comparator is required in a surface-mount form factor. The TSSOP package suits space-constrained designs. Consider the propagation delay specifications for timing-critical paths. Evaluate the power consumption against system battery life requirements. Verify input compatibility with the driving logic family.

Comparators Part Context

The CD4585B series comprises CMOS 4-bit magnitude comparators. The CD4585BPWR variant specifically denotes the plastic TSSOP packaging option within the broader CD4585B family. This family includes ceramic DIP and other plastic package variants. The device belongs to the standard 4000-series CMOS logic line, known for wide voltage operation and low power consumption.

Comparators Replacement Considerations

Compatible substitutes include CD4585BE (PDIP) and CD4585BPW (TSSOP). Verify pinout compatibility before substitution. Ensure electrical parameters such as propagation delay and output current meet circuit requirements. Package dimensions differ between PDIP and TSSOP versions.
