Frequently Asked Questions
What comparison functions does the CD4585BF3A perform?
The CD4585BF3A performs a 4-bit magnitude comparison between two 4-bit binary inputs (A and B), producing three output signals: A greater than B (A>B), A equal to B (A=B), and A less than B (A<B). These outputs can be directly used in sorting, range detection, and conditional branching circuits in digital logic designs.
Can the CD4585BF3A be cascaded for wider comparisons?
Yes, the CD4585BF3A is specifically designed to be cascadable. It includes cascade inputs that accept the A>B, A=B, and A<B outputs from a less-significant stage, allowing multiple devices to be chained together to compare 8-bit, 16-bit, or larger word widths. This makes it useful in multi-stage comparison circuits for wider binary number magnitude evaluation.
What logic family does the CD4585BF3A belong to?
The CD4585BF3A belongs to the 4000/14000/40000 CMOS logic family, a versatile family that operates over a very wide supply voltage range (typically 3V to 18V). CMOS logic provides very low static power consumption and high noise immunity, making it well suited for industrial, military, and battery-powered applications requiring reliable logic operation under varying supply conditions.
What package does the CD4585BF3A come in?
The CD4585BF3A is packaged in a 16-pin ceramic DIP (CDIP), identified by the JESD-30 code R-GDIP-T16. The hermetically sealed ceramic package provides excellent protection against moisture and contaminants, making it the preferred package type for military-grade and high-reliability industrial applications requiring long-term operational stability and resistance to harsh environmental conditions.
