74F00SC NAND Gate IC Equivalent & Substitute Parts

Part Overview

The 74F00SC is a 4-channel 2-input NAND gate logic IC manufactured by onsemi in a 14-SOIC surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The 74F00 series represents a standard TTL logic family with consistent functional performance across qualified manufacturers and packaging variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F00SC is determined by strict equivalence across the following parameters: logic type (NAND Gate), circuit count (4 channels), input count (2 inputs per channel), supply voltage range (4.5V ~ 5.5V), output current specifications (1mA high, 20mA low), input logic thresholds (0.8V low, 2V high), propagation delay (5ns @ 5V, 50pF), operating temperature range (0°C ~ 70°C), and surface mount configuration.

The substitute parts are grouped as follows:

Direct Manufacturer Equivalent (SN74F00DR): Identical electrical parameters and 14-SOIC package footprint. Supplied in Tape & Reel packaging. Active product status with ROHS3 compliance.

Similar Manufacturer Part (SN74F00NSR): Identical electrical parameters with 14-SO package variant (0.209" width vs. 0.154" width). Supplied in Tape & Reel packaging. Active product status with ROHS3 compliance. Package footprint difference requires PCB layout verification.

Parametric Equivalent (SN74F00D): Identical electrical parameters and 14-SOIC package footprint. Supplied in Tube packaging. Last Time Buy product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Active Production: SN74F00DR is the preferred substitute. It maintains identical electrical specifications and package footprint to the 74F00SC, carries Active product status from Texas Instruments, and is ROHS3 compliant. Tape & Reel packaging supports automated assembly processes.

For PCB Layout Compatibility: SN74F00D provides identical electrical performance and 14-SOIC footprint matching. However, Last Time Buy status indicates limited future availability. Tube packaging is suitable for manual assembly or lower-volume production.

For Package Variant Applications: SN74F00NSR is electrically equivalent but uses a 14-SO package with different physical dimensions (0.209" width vs. 0.154" width). This part is suitable only if PCB layout has been designed for the wider 14-SO footprint. Active product status and ROHS3 compliance are maintained.

Frequently Asked Questions (FAQ)

Q: Can SN74F00DR be used as a direct replacement for 74F00SC without PCB modifications?

A: Yes. SN74F00DR is electrically and mechanically identical to 74F00SC. Both use the 14-SOIC package with 0.154" width and 3.90mm pitch. No PCB layout changes are required.

Q: What is the difference between SN74F00DR and SN74F00NSR?

A: Both parts are electrically identical NAND gate ICs with matching electrical specifications. The primary difference is the package: SN74F00DR uses 14-SOIC (0.154" width), while SN74F00NSR uses 14-SO (0.209" width). PCB footprints are not interchangeable without layout redesign.

Q: Why is 74F00SC listed as obsolete?

A: The 74F00SC is an onsemi product that has reached end-of-life status. Active equivalents from Texas Instruments (SN74F00DR and SN74F00NSR) are available to support continued design and production requirements.

Q: Is SN74F00D suitable for new production?

A: SN74F00D carries Last Time Buy status, indicating limited future availability. While electrically and mechanically equivalent to 74F00SC, it is not recommended for new designs. SN74F00DR is the preferred choice for ongoing production.

Q: Are all substitute parts ROHS3 compliant?

A: SN74F00DR, SN74F00NSR, and SN74F00D are all ROHS3 compliant. The original 74F00SC is listed as REACH Unaffected. All parts meet current environmental compliance standards.

Q: What packaging options are available for the substitute parts?

A: SN74F00DR is supplied in Tape & Reel (TR) packaging for automated assembly. SN74F00D is supplied in Tube packaging for manual assembly or lower-volume applications. SN74F00NSR is also supplied in Tape & Reel packaging.
