Substitute Part Grouping Explanation

Substitution of the 74F08PC is determined by strict equivalence across the following critical parameters:

• Logic function: AND gate with 4 channels and 2 inputs per channel
• Electrical specifications: 4.5V to 5.5V supply voltage, 1mA/20mA output current, 0.8V/2V input logic levels, 5.6ns propagation delay
• Physical form factor: 14-DIP through-hole package with 0.300" (7.62mm) pitch
• Series classification: 74F logic family

The SN74F08N from Texas Instruments meets all substitution criteria, maintaining identical logic configuration, electrical performance, and mechanical compatibility while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The SN74F08N is a direct functional and electrical equivalent to the 74F08PC. Both components are classified under ECCN EAR99 and maintain REACH Unaffected status, ensuring regulatory compliance across both legacy and current implementations. The primary distinction is product status: the 74F08PC is obsolete, while the SN74F08N maintains active status with documented availability. For new designs, maintenance applications, or system upgrades requiring the 74F08 AND gate function, the SN74F08N from Texas Instruments provides equivalent performance with assured supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the SN74F08N directly replace the 74F08PC in existing circuits?

A: Yes. Both components share identical logic configuration (4-channel AND gate), electrical specifications (supply voltage, output current, input logic levels, propagation delay), and physical package dimensions (14-DIP, 0.300" pitch). Pin-for-pin substitution is valid.

Q: What is the primary reason to substitute the 74F08PC?

A: The 74F08PC is classified as obsolete. The SN74F08N is an active product with current manufacturing and documented availability, making it the appropriate choice for ongoing support and new implementations.

Q: Are there packaging differences between these parts?

A: Both components use 14-DIP through-hole packages with identical 0.300" (7.62mm) pitch. The 74F08PC is supplied in standard packaging, while the SN74F08N is supplied in tube packaging. Both are mechanically compatible with standard DIP sockets and PCB layouts.

Q: Do compliance certifications differ between the two parts?

A: No. Both the 74F08PC and SN74F08N maintain identical REACH Unaffected status and EAR99 ECCN classification, ensuring regulatory equivalence.

Q: What are the critical electrical parameters for substitution?

A: Supply voltage (4.5V–5.5V), output current (1mA/20mA), input logic levels (0.8V low, 2V high), and propagation delay (5.6ns @ 5V, 50pF) must remain constant. Both parts meet these specifications identically.
