Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74LS00NSRG4 is determined by strict equivalence across the following critical parameters:

• Logic function: NAND Gate with identical 4-channel, 2-input configuration
• Electrical specifications: Supply voltage range (4.75V ~ 5.25V), output current ratings (400µA, 8mA), input logic levels (0.8V low, 2V high), and propagation delay (15ns @ 5V, 15pF)
• Physical packaging: 14-SOIC surface mount form factor with identical dimensions (0.209", 5.30mm width)
• Compliance standards: ROHS3 compliance and MSL rating of 1 (Unlimited)
• Operating temperature range: 0°C ~ 70°C

The SN74LS00NSR qualifies as a direct substitute based on identical electrical and mechanical parameters across all specified criteria.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS00NSR is the direct equivalent for the discontinued SN74LS00NSRG4. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the SN74LS00NSR is currently active with substantial inventory availability (2,000,300 pieces), whereas the SN74LS00NSRG4 is discontinued. Both parts carry ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility. The SN74LS00NSR is suitable for direct replacement in applications requiring the 74LS NAND gate logic function without design modification.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS00NSR replace the SN74LS00NSRG4 in existing designs?

A: Yes. The SN74LS00NSR is electrically and mechanically identical to the SN74LS00NSRG4 across all specified parameters, including logic function, supply voltage, output current, input logic levels, propagation delay, operating temperature range, and 14-SOIC packaging. No circuit redesign is required.

Q: What is the difference between SN74LS00NSRG4 and SN74LS00NSR?

A: The parts are functionally equivalent. The primary difference is product status: SN74LS00NSRG4 is discontinued, while SN74LS00NSR is active with full inventory availability. Both share identical electrical specifications and packaging.

Q: Are there packaging differences between these parts?

A: No. Both the SN74LS00NSRG4 and SN74LS00NSR use the 14-SOIC surface mount package with identical dimensions (0.209", 5.30mm width). PCB layout and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited), REACH unaffected status, and identical ECCN and HTSUS classifications.

Q: What is the operating temperature range for these parts?

A: Both parts operate within 0°C to 70°C (TA). This specification is identical for the SN74LS00NSRG4 and SN74LS00NSR.
