74F08SJ AND Gate IC Equivalent & Substitute Parts

Part Overview

The 74F08SJ is a 4-channel 2-input AND gate logic IC manufactured by onsemi in 14-SOP surface mount packaging. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The 74F08 series provides standard AND gate functionality with consistent electrical characteristics across compatible variants from multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74F08SJ are qualified based on matching the following critical parameters: logic type (AND 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 (5.6ns @ 5V, 50pF), operating temperature range (0°C ~ 70°C), and surface mount mounting type. All substitute parts maintain the 74F base product number designation and are compatible with the same functional requirements.

Substitutes are grouped by packaging configuration and product status. Direct substitutes share identical electrical performance and differ only in supplier packaging format (Tape & Reel versus Tube) or package case dimensions within the 14-SOIC family.

Parameter Comparison

Engineering Selection Recommendations

For new designs, SN74F08NSR or SN74F08DR from Texas Instruments are preferred due to active product status and ROHS3 compliance. Both parts maintain identical electrical specifications to the 74F08SJ while offering long-term availability and regulatory compliance.

SN74F08NSR is supplied in Tape & Reel format, suitable for automated assembly processes. SN74F08DR is also supplied in Tape & Reel format with the same active status.

SN74F08D carries Last Time Buy status and should be evaluated only for legacy system maintenance where existing inventory or specific packaging requirements justify its selection. This part is supplied in Tube format.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Moisture sensitivity level remains MSL 1 (Unlimited) across all variants, indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can SN74F08NSR directly replace 74F08SJ in existing designs? A: Yes. Both parts share identical electrical specifications, supply voltage range, output current ratings, input logic thresholds, and propagation delay. The primary difference is packaging format (Tape & Reel versus unspecified) and manufacturer. PCB layout compatibility depends on package case dimensions; both use 14-SOIC but with different width specifications (0.209" versus 0.209").

Q: What is the difference between SN74F08D and SN74F08DR? A: Both parts are electrically identical 4-channel 2-input AND gates with matching specifications. The primary difference is packaging format: SN74F08D is supplied in Tube format, while SN74F08DR is supplied in Tape & Reel (TR) format. SN74F08DR has active product status; SN74F08D is Last Time Buy. For new production, SN74F08DR is recommended.

Q: Are there package case dimension differences between substitutes? A: Yes. The 74F08SJ and SN74F08NSR both use 14-SOIC with 0.209" width (5.30mm). The SN74F08D and SN74F08DR use 14-SOIC with 0.154" width (3.90mm). Verify PCB footprint compatibility before substitution.

Q: Do all substitutes meet current compliance standards? A: Texas Instruments substitutes (SN74F08NSR, SN74F08D, SN74F08DR) are ROHS3 compliant and REACH unaffected. All parts maintain MSL 1 (Unlimited) moisture sensitivity level, requiring no special storage conditions.

Q: Why is 74F08SJ marked as obsolete? A: The 74F08SJ is an onsemi product classified as obsolete. Active alternatives from Texas Instruments ensure continued availability and support for 74F08 AND gate functionality.
