MC14008BCPG

Specialty Logic Overview

The MC14008BCPG is a 4-bit full adder constructed with CMOS P-Channel and N-Channel enhancement mode devices. It features four full adders with fast internal look-ahead carry output for high-speed binary addition. The device operates within a supply voltage range of 3.0 Vdc to 18 Vdc and includes diode protection on all inputs. All outputs are buffered, allowing it to drive two Low-Power TTL loads or one Low-Power Schottky TTL load over the rated temperature range.

Specialty Logic Feature Summary

• Features fast parallel carry output bit for high-speed operation when cascaded with other adders in a system.
• Includes double diode protection on all inputs to guard against damage from high static voltages or electric fields.
• All outputs are buffered, enabling direct driving of standard logic loads without external buffering.

Specialty Logic Applications

• Binary addition circuits
• Arithmetic applications requiring fast carry propagation
• Cascaded multi-bit adder configurations

Specialty Logic Procurement Notes

Verify the package suffix 'P' corresponds to the PDIP-16 (Case 648) physical form factor required for your board layout. Confirm that the specific revision of the datasheet matches your design requirements, as electrical characteristics such as propagation delay may vary slightly between revisions. Ensure input pins are tied to appropriate logic levels if unused to prevent floating states.

Specialty Logic Selection Notes

Select this component when a monolithic 4-bit arithmetic solution is needed with wide supply voltage flexibility. It serves as a pin-for-pin replacement for corresponding CD4008B devices, facilitating direct upgrades or cross-manufacturer sourcing. Consider its buffered outputs and TTL compatibility if interfacing with legacy logic families in mixed-voltage systems.

Specialty Logic Part Context

This part belongs to the B-Suffix Series of CMOS gates manufactured by onsemi. These devices utilize complementary MOS technology in a single monolithic structure, prioritizing low power dissipation and high noise immunity. The series is designed for general-purpose digital logic applications where robust performance across a wide temperature range is essential.

Specialty Logic Replacement Considerations

The datasheet explicitly identifies the CD4008B as a pin-for-pin replacement equivalent. When substituting, verify that the alternative manufacturer's device maintains compatible supply voltage ranges and output drive capabilities to ensure functional parity in the existing circuit design.
