MC14008BDR2G

Specialty Logic Overview

The MC14008BDR2G is a four-bit binary full adder and subtractor from the 4000 series of logic integrated circuits. Manufactured by onsemi, this component utilizes CMOS technology and is housed in a 16-lead SOIC surface-mount package. It operates within a supply voltage range of 3 V to 18 V and supports standard voltages including 3.3 V, 5 V, 9 V, 12 V, and 15 V. The device features propagation delays of 800 ns, 320 ns, and 230 ns, with low-level and high-level output currents of 4.2 mA and -4.2 mA respectively. Static current consumption is specified at 20 uA, and power dissipation reaches 500 mW. It functions across an industrial temperature range from -55 C to +125 C.

Specialty Logic Feature Summary

• Performs binary addition and subtraction operations using a single-channel architecture.
• CMOS construction ensures low static power consumption and high noise immunity.
• Integrated diode protection on inputs enhances signal integrity under transient conditions.

Specialty Logic Applications

• Digital arithmetic processing units requiring binary addition or subtraction
• Counting circuits and address decoding systems
• Industrial control logic interfacing

Specialty Logic Procurement Notes

Verify the specific suffix 'G' indicates lead-free and RoHS compliance status according to manufacturer documentation. Confirm the SOIC-16 package dimensions match PCB footprint requirements. Check for automotive qualification prefixes if operating in harsh environments. Ensure supply chain sources provide valid datasheets matching the MC14008BDR2G designation to avoid confusion with non-compliant variants.

Specialty Logic Selection Notes

Select this component when a dedicated four-bit arithmetic logic function is required within a CMOS system. It serves as a direct replacement for legacy CD4008 devices in existing designs. Consider the wide supply voltage range for flexibility in mixed-voltage applications. Evaluate thermal management needs given the 500 mW power dissipation rating at maximum operating temperatures.

Specialty Logic Part Context

This part belongs to the MC14000B series of CMOS logic devices produced by onsemi. It is functionally equivalent to the industry-standard CD4008. The DR2 suffix denotes tape-and-reel packaging suitable for automated surface-mount assembly processes. The G suffix typically signifies environmental compliance attributes defined by the manufacturer.

Specialty Logic Replacement Considerations

CD4008B is a verified functional substitute offering identical pinout and electrical characteristics. Other compatible alternatives include MC14008B without the reel suffix for bulk handling. Verify compatibility with existing board layouts when switching between DIP and SOIC packages.
