CD74HC283MT Equivalent & Substitute Parts

Part Overview

The CD74HC283MT is a 4-bit binary full adder with fast carry logic manufactured by Texas Instruments. This surface-mount IC operates across a supply voltage range of 2V to 6V and is housed in a 16-SOIC package. The device is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design requirements and production needs. The CD74HC283MT remains available in inventory (852 Pcs) and maintains full ROHS3 compliance and REACH unaffected status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC283MT is determined by strict equivalence across the following critical parameters:

• Logic Type: Binary Full Adder with Fast Carry (4-bit configuration)
• Supply Voltage: 2V ~ 6V operating range
• Number of Bits: 4-bit architecture
• Operating Temperature Range: -55°C ~ 125°C
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The CD74HC283M96 meets all substitution criteria as a direct equivalent from the same manufacturer, differing only in packaging format (Cut Tape and Digi-Reel) and product status (Active vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The CD74HC283M96 is a direct functional equivalent to the CD74HC283MT. Both parts share identical electrical specifications, thermal characteristics, and mechanical package dimensions. The primary distinction is product status: the CD74HC283M96 maintains Active status with higher inventory availability (1859 Pcs), while the CD74HC283MT is discontinued at DiGi Electronics.

For new designs or production continuity, the CD74HC283M96 is the appropriate selection. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The packaging format difference (Cut Tape and Digi-Reel for the M96 variant) does not affect electrical or mechanical compatibility and is a supply chain consideration only.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC283M96 replace the CD74HC283MT in existing designs?

A: Yes. The CD74HC283M96 is electrically and mechanically identical to the CD74HC283MT. Both devices feature the same 4-bit binary full adder logic, supply voltage range (2V ~ 6V), operating temperature range (-55°C ~ 125°C), and 16-SOIC package dimensions. Direct substitution is valid without circuit modification.

Q: What is the difference between CD74HC283MT and CD74HC283M96?

A: The devices are functionally equivalent. The CD74HC283MT is discontinued at DiGi Electronics, while the CD74HC283M96 maintains Active product status. The M96 variant is supplied in Cut Tape and Digi-Reel formats, whereas the MT variant uses standard packaging. Electrical and mechanical specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the CD74HC283MT and CD74HC283M96 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does the 16-SOIC package dimension remain the same for both parts?

A: Yes. Both parts use the 16-SOIC package with identical dimensions of 0.154" width (3.90mm). PCB footprints and assembly processes are interchangeable.

Q: What is the Moisture Sensitivity Level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
