CD4063BNSR

Comparators Overview

The CD4063BNSR is a CMOS 4-bit magnitude comparator manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 15 V and supports junction temperatures from -55°C to 125°C. The device is housed in a 16-lead Small Outline Package (NS). It compares two 4-bit binary words, providing active-high outputs for A>B, A<B, and A=B conditions. Typical propagation delay is 250 ns at 10 V supply.

Comparators Feature Summary

• Provides distinct logic outputs indicating whether input A is greater than, less than, or equal to input B
• Supports cascading configurations to expand comparison capability to 8, 12, or 16 bits
• Operates with medium-speed performance suitable for general digital logic applications

Comparators Applications

• Digital data comparison circuits
• Address decoding systems
• Cascaded multi-bit magnitude comparison modules

Comparators Procurement Notes

Verify the package type matches the required footprint, as the NS suffix denotes a 16-lead Small Outline Package. Confirm the operating temperature range meets system requirements, specifically the -55°C to 125°C specification. Ensure the supply voltage constraints align with the design's power rails. Check for any specific marking or revision codes if strict traceability is required for the manufacturing process.

Comparators Selection Notes

Select this component when a dedicated 4-bit magnitude comparison function is needed without external logic gates. Consider the 250 ns typical delay for timing-critical paths. Evaluate the need for cascading capabilities if wider bit comparisons are anticipated. Verify that the CMOS input characteristics match the driving source impedance and voltage levels of the upstream circuitry.

Comparators Part Context

This part belongs to the CD4063B family of CMOS logic devices. It serves as a fundamental building block for arithmetic logic units and digital control systems requiring direct binary value comparison. The standard SOIC package facilitates surface-mount assembly in compact electronic designs.

Comparators Replacement Considerations

Check for other CD4063B variants with different suffixes such as 'D' for DIP packages if through-hole mounting is required. Verify compatibility with generic CMOS 4-bit comparators only if pinout and electrical specifications are identical.
