CD4585BEG4

Comparators Overview

The CD4585BEG4 is a CMOS 4-bit magnitude comparator from the Texas Instruments 4000B series. It performs logical comparisons between two 4-bit binary words, indicating whether A is less than, equal to, or greater than B via active-high outputs. The device operates within a supply voltage range of 3 V to 18 V and supports a wide temperature range from -55 °C to +125 °C. It features a 16-lead plastic dual-in-line package (PDIP) with through-hole mounting. Propagation delays vary by voltage: 160 ns at 15 V, 250 ns at 10 V, and 600 ns at 5 V under 50 pF load conditions.

Comparators Feature Summary

• Performs 4-bit magnitude comparison with dedicated outputs for less-than, equal-to, and greater-than relationships
• Utilizes CMOS technology for low power consumption and high noise immunity
• Supports cascading capabilities for expanding comparison bit-width beyond four bits

Comparators Applications

• Digital arithmetic logic units requiring magnitude evaluation
• Control systems for threshold detection and decision making
• Data acquisition systems for signal level validation

Comparators Procurement Notes

Verify the component status carefully as some sources indicate discontinuation at specific distributors. Confirm the E suffix denotes the standard plastic DIP package and G4 indicates lead-free/RoHS compliance. Ensure the ordering part number matches the required package type and environmental specifications for your design.

Comparators Selection Notes

Select this component when a 4-bit digital magnitude comparison is required in a through-hole design. Consider the propagation delay characteristics relative to your system clock speed. Verify that the operating voltage range aligns with your circuit's power supply rails and that the PDIP package fits your PCB layout constraints.

Comparators Part Context

This part belongs to the Texas Instruments CD4000B series of CMOS logic devices. The CD4585B variant specifically functions as a magnitude comparator. The EG4 suffix typically signifies a lead-free version compliant with RoHS directives, packaged in a standard 16-pin plastic dual-in-line format suitable for general-purpose digital logic applications.

Comparators Replacement Considerations

The CD4585BE is the non-leaded equivalent without the G4 suffix. Other 4000-series comparators may offer different pinouts or performance metrics. Verify compatibility before substitution.
