CD4585BEE4

Comparators Overview

The CD4585BEE4 is a CMOS 4-bit magnitude comparator from the Texas Instruments CD4585B series. It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range of -55 °C to +125 °C. The device features active high outputs for A < B, A = B, and A > B comparisons. Propagation delay times are specified as 60 ns and 80 ns under standard test conditions. Maximum output currents are rated at -6.8 mA for high level and 6.8 mA for low level. The component is housed in a 16-lead PDIP package.

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 wide supply voltage tolerance.
• Provides active high logic outputs compatible with standard digital interfaces.

Comparators Applications

• Digital arithmetic logic units requiring magnitude evaluation
• Address decoding systems
• Error detection circuits

Comparators Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance and RoHS status against current manufacturer documentation. Confirm the PDIP-16 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Comparators Selection Notes

Select this component when a 4-bit magnitude comparison function is required within a CMOS logic family. The wide supply voltage range allows flexibility in system power design. Consider the propagation delay characteristics for timing-critical applications. Verify that the through-hole packaging aligns with your assembly capabilities.

Comparators Part Context

The CD4585BEE4 belongs to the CD4585B series of 4-bit magnitude comparators. It is part of the broader 4000-series CMOS logic family, known for high noise immunity and broad operating voltage ranges. The EE4 suffix typically denotes environmental compliance features such as lead-free construction.

Comparators Replacement Considerations

Compatible substitutes include other 4-bit magnitude comparators from the same logic family or equivalent parts from other manufacturers offering similar PDIP-16 packages and electrical characteristics. Verify pin compatibility and logical function equivalence before substitution.
