CD4585BPWG4

Comparators Overview

The CD4585BPWG4 is a CMOS 4-bit magnitude comparator from the Texas Instruments CD4585B series, housed in a 16-pin TSSOP package. It performs A < B, A = B, and A > B logic functions with active high outputs. Operating voltage ranges from 3 V to 18 V, with a maximum supply current of 100 µA. Output currents are ±6.8 mA. Propagation delays are 60 ns at 5 V and 80 ns at 15 V. The device operates within a temperature range of -55 °C to +125 °C.

Comparators Feature Summary

• Performs 4-bit magnitude comparison with dedicated outputs for less than, equal to, and greater than conditions.
• Features active high outputs for direct interfacing with digital logic systems.
• Supports wide supply voltage operation from 3 V to 18 V.
• Designed for industrial temperature environments ranging from -55 °C to +125 °C.

Comparators Applications

• Digital data processing systems requiring magnitude evaluation
• Industrial control logic circuits
• Measurement instrumentation

Comparators Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the 16-TSSOP package dimensions match the design footprint requirements. Ensure the operating environment stays within the specified -55 °C to +125 °C range to maintain performance specifications.

Comparators Selection Notes

Select this component when a 4-bit magnitude comparison function is required in a surface-mount design. The TSSOP-16 package offers a compact solution compared to through-hole alternatives like the PDIP variant. Consider the propagation delay characteristics relative to system clock speeds and ensure the power supply voltage remains within the 3 V to 18 V operational window.

Comparators Part Context

This part belongs to the CD4585B family of CMOS 4-bit magnitude comparators. It provides logical comparison capabilities between two 4-bit binary words. The BPWG4 designation specifies the TSSOP package and green (RoHS compliant) manufacturing process. It serves as a fundamental building block for arithmetic logic units and decision-making circuits in digital electronics.

Comparators Replacement Considerations

The CD4585BE is a pin-compatible through-hole alternative. For surface-mount needs, verify if other CD4585 variants meet the specific package and electrical requirements. Cross-reference datasheets to confirm identical logic functions and output drive capabilities before substitution.
