CD4560BF

Specialty Logic Overview

The CD4560BF is a CMOS NBCD (Natural Binary Coded Decimal) adder/subtractor manufactured by Harris Corporation. It operates within a supply voltage range of 3V to 18V and features an input threshold compatible with TTL logic levels. The device is housed in a 16-pin Ceramic Dual In-Line Package (CDIP-16). It supports bidirectional arithmetic operations, allowing for both addition and subtraction functions through control inputs.

Specialty Logic Feature Summary

• CMOS technology ensures low power consumption and high noise immunity.
• Bidirectional capability allows the circuit to perform both addition and subtraction operations.
• TTL-compatible input thresholds facilitate direct interfacing with standard logic families.
• Ceramic dual in-line package provides robust physical protection and thermal stability.

Specialty Logic Applications

• Digital arithmetic processing units requiring decimal-based calculations
• Control systems utilizing NBCD data formats
• Industrial instrumentation involving numeric data manipulation

Specialty Logic Procurement Notes

Verify the manufacturer origin, as Harris Corporation assets have been acquired by other entities. Confirm the package type is ceramic DIP-16 rather than plastic variants. Check RoHS compliance status, as original Harris parts may not meet current environmental standards. Ensure the suffix 'BF' denotes the specific ceramic package variant required for your application.

Specialty Logic Selection Notes

Select this component when NBCD arithmetic is required rather than pure binary. Consider the CD4560BF for applications needing bidirectional add/subtract functionality in a single IC. Evaluate the ceramic package requirements against cost constraints, as plastic alternatives like CD4560B exist. Verify voltage compatibility with the 3V to 18V operating range.

Specialty Logic Part Context

This part belongs to the 4000/14000/40000 series of CMOS logic devices originally developed by Harris Corporation. These components are widely recognized for their versatility in digital logic applications. The CD4560BF specifically addresses arithmetic needs within this family, complementing counters and decoders available from the same manufacturer.

Specialty Logic Replacement Considerations

• CD4560B (Plastic DIP variant)
• HEF4560BT (NXP equivalent)
