74F08SC AND Gate IC Equivalent & Substitute Parts

Part Overview

The 74F08SC is a 4-channel 2-input AND 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 procurement. The 74F08 series provides standard TTL-compatible AND gate functionality suitable for digital logic applications requiring fast propagation delays and reliable switching performance.

Substitute Part Grouping Explanation

Substitute parts for the 74F08SC are classified based on electrical and mechanical compatibility within the 74F08 series. All substitute candidates maintain identical logic functionality, electrical performance characteristics, and supply voltage requirements. Substitution eligibility is determined by the following criteria:

Primary Substitution Criteria:

• Logic Type: AND Gate (4 channels, 2 inputs per channel)
• Voltage Supply: 4.5V ~ 5.5V
• Output Current Ratings: 1mA (High) / 20mA (Low)
• Input Logic Levels: 0.8V (Low) / 2V (High)
• Propagation Delay: 5.6ns @ 5V, 50pF
• Operating Temperature: 0°C ~ 70°C
• Mounting Type: Surface Mount
• Base Product Number: 74F08

Package Considerations:

• Direct substitutes use 14-SOIC (0.154", 3.90mm Width) packaging
• Similar substitutes use 14-SO (0.209", 5.30mm Width) packaging with identical electrical performance but different physical dimensions

Engineering Selection Recommendations

Direct Substitutes (Identical Package):

SN74F08DR is the primary recommended substitute for the 74F08SC. This Texas Instruments part maintains active product status, ROHS3 compliance, and identical electrical and mechanical specifications. The Tape & Reel packaging format supports high-volume production environments. With 4050 units in stock, this part offers immediate availability for replacement designs.

SN74F08D provides an alternative direct substitute with Last Time Buy status. This part is supplied in Tube packaging and maintains full electrical compatibility. Selection of this part should account for its transitional product status and packaging format requirements.

Similar Substitute (Modified Package):

SN74F08NSR is electrically equivalent to the 74F08SC but uses a 14-SO package (0.209", 5.30mm Width) instead of the standard 14-SOIC (0.154", 3.90mm Width). This part maintains active product status and ROHS3 compliance. PCB layout modifications are required to accommodate the wider package footprint. This option is suitable only when physical space constraints permit the larger package dimensions.

Frequently Asked Questions (FAQ)

Q: Can SN74F08NSR be used as a direct replacement for 74F08SC on existing PCBs?

A: No. SN74F08NSR uses a 14-SO package (0.209", 5.30mm Width) compared to the 74F08SC's 14-SOIC package (0.154", 3.90mm Width). PCB footprint modification is required. For direct PCB compatibility without layout changes, use SN74F08DR or SN74F08D.

Q: What is the difference between SN74F08D and SN74F08DR?

A: Both parts are electrically identical with matching specifications. The primary difference is packaging format: SN74F08D is supplied in Tube packaging, while SN74F08DR is supplied in Tape & Reel format. SN74F08DR has active product status; SN74F08D is Last Time Buy. For new designs, SN74F08DR is preferred.

Q: Are all substitute parts RoHS compliant?

A: SN74F08D, SN74F08DR, and SN74F08NSR are all ROHS3 compliant. The original 74F08SC does not specify RoHS status. All parts maintain REACH Unaffected status.

Q: What is the moisture sensitivity level for these parts?

A: All parts in this comparison, including the 74F08SC and all substitutes, have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in terms of electrical performance?

A: Yes. All listed parts maintain identical electrical specifications: 4.5V ~ 5.5V supply voltage, 1mA/20mA output current, 0.8V/2V input logic levels, and 5.6ns propagation delay at 5V with 50pF load. Electrical performance is fully interchangeable across all substitutes.
