Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74LS00D is determined by strict equivalence across the following critical parameters:

• Logic Type: NAND Gate (4 channels, 2 inputs per channel)
• Electrical Specifications: Supply voltage 4.75V ~ 5.25V, output current 400µA/8mA, input logic levels 0.8V/2V, propagation delay 15ns @ 5V with 15pF load
• Operating Temperature Range: 0°C ~ 70°C
• Package: 14-SOIC surface mount form factor
• Compliance: ROHS3 compliant, MSL Level 1

The SN74LS00DR meets all these criteria as a direct substitute, with identical electrical and mechanical specifications. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS00DR is the direct equivalent substitute for the SN74LS00D. Both components are manufactured by Texas Instruments with identical electrical characteristics, operating parameters, and package specifications. The SN74LS00DR maintains active product status, ensuring continued availability and supply chain reliability. Both parts carry ROHS3 compliance and MSL Level 1 rating, meeting environmental and moisture sensitivity requirements. Selection between these parts should be based on packaging format availability: the SN74LS00D was supplied in Tube packaging, while the SN74LS00DR is available in Cut Tape (CT) and Digi-Reel® formats.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS00DR directly replace the SN74LS00D in existing designs?

A: Yes. The SN74LS00DR is electrically and mechanically identical to the SN74LS00D. Both components feature the same 14-SOIC package, supply voltage range, output current specifications, input logic levels, and propagation delay characteristics. No circuit modifications are required.

Q: What is the difference between the SN74LS00D and SN74LS00DR?

A: The primary differences are product status and packaging format. The SN74LS00D is discontinued and was supplied in Tube packaging. The SN74LS00DR is an active product available in Cut Tape (CT) and Digi-Reel® formats. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both the SN74LS00D and SN74LS00DR carry identical ROHS3 compliance status and Moisture Sensitivity Level 1 (Unlimited) rating. REACH status is unaffected for both parts.

Q: What packaging formats are available for the substitute part?

A: The SN74LS00DR is supplied in Cut Tape (CT) and Digi-Reel® formats. The original SN74LS00D was supplied in Tube packaging. Selection should be based on assembly process requirements and handling procedures.

Q: Is the 14-SOIC package identical between both parts?

A: Yes. Both components use the 14-SOIC package with 0.154" width and 3.90mm dimensions. PCB footprints and soldering procedures are identical.
