Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC283D,653 is determined by the following critical parameters:

• Logic Function: Binary full adder with fast carry (4-bit)
• Package Type: 16-SOIC form factor with identical pin pitch and dimensions
• Supply Voltage Compatibility: 2V ~ 6V operating range
• Bit Width: 4-bit configuration
• Mounting Technology: Surface mount capability
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The CD74HC283M96 from Texas Instruments meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The CD74HC283M96 serves as a direct functional substitute for the 74HC283D,653. Both components share identical logic function, bit width, package geometry, and supply voltage specifications. The Texas Instruments variant offers an extended lower operating temperature limit (-55°C versus -40°C), providing broader environmental coverage. The CD74HC283M96 maintains active product status, ensuring long-term availability and supply chain stability compared to the obsolete NXP part. Both components satisfy ROHS3 compliance and REACH requirements, supporting equivalent regulatory and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC283M96 replace the 74HC283D,653 in existing designs?

A: Yes. Both components are 4-bit binary full adders with identical supply voltage ranges (2V ~ 6V), package dimensions (16-SOIC), and pin configurations. Direct substitution is supported without circuit modification.

Q: What is the difference in operating temperature ranges?

A: The 74HC283D,653 operates from -40°C to 125°C, while the CD74HC283M96 operates from -55°C to 125°C. The Texas Instruments part provides extended low-temperature performance. For applications within the -40°C to 125°C window, both parts are equivalent.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 74HC283D,653 and CD74HC283M96 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: Why is the NXP part listed as obsolete?

A: The 74HC283D,653 has reached end-of-life status with NXP. The CD74HC283M96 from Texas Instruments remains in active production, providing continuity for applications requiring 4-bit binary full adder functionality.

Q: Are the package specifications identical?

A: Yes. Both components use the 16-SOIC package with 0.154" width and 3.90mm dimensions, ensuring mechanical and electrical compatibility on PCB layouts designed for either part.
