CD4008BD3

Specialty Logic Overview

The CD4008BD3 is a 4-bit full adder integrated circuit manufactured by Harris Corporation. It belongs to the 4000/14000/40000 series of CMOS logic devices. The component features a single functional unit with four bits of processing capability, designed for arithmetic operations. It utilizes a 16-lead ceramic dual in-line package (CDIP16) with metal-sealed cofired construction. The device operates within a supply voltage range of 3V to 18V and supports a wide operating temperature range from -55°C to 125°C.

Specialty Logic Feature Summary

• Implements 4-bit binary addition with carry-in and carry-out capabilities
• Utilizes standard CMOS technology compatible with the 4000 series logic family
• Constructed in a hermetically sealed ceramic dual in-line package for durability

Specialty Logic Applications

• Digital arithmetic logic units requiring multi-bit addition
• Address calculation circuits in embedded systems
• Data processing modules in industrial control equipment

Specialty Logic Procurement Notes

Verify the specific manufacturer source, as Harris Corporation assets have been acquired by other entities such as Renesas Electronics. Confirm that the CDIP16 ceramic package matches the required form factor for your application. Ensure compliance with RoHS regulations if applicable, as older stock may not meet current environmental standards. Validate pinout compatibility with existing PCB layouts before procurement.

Specialty Logic Selection Notes

Select this component when a dedicated 4-bit full adder is required rather than using multiple discrete gates. The CDIP16 package is suitable for through-hole mounting in high-reliability applications. Consider the 4000 series speed and power characteristics against modern alternatives if higher performance is needed. Verify that the operating voltage range aligns with the system power supply.

Specialty Logic Part Context

This part is part of the extensive 4000 series CMOS logic family, which provides basic logic functions including adders, counters, and flip-flops. The BD3 suffix typically denotes the ceramic DIP package variant. These components are widely used in legacy designs and industrial environments where long-term availability and robustness are prioritized over miniaturization.

Specialty Logic Replacement Considerations

Equivalent parts include the CD4008BE or CD4008B from various manufacturers offering plastic DIP packages. For direct ceramic replacements, verify availability from distributors holding Harris/Renesas inventory. Ensure logical equivalence for 4-bit addition functionality when substituting.
