SN74F08DRG4 Equivalent & Substitute Parts

Part Overview

The SN74F08DRG4 is a 4-channel AND gate logic IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is classified as discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement. The SN74F08DRG4 operates within the 74F logic family and provides dual-input AND gate functionality suitable for digital logic applications requiring fast propagation delays and standard TTL-compatible voltage levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74F08DRG4 is determined by strict equivalence across the following critical parameters:

• Logic function: 4-channel AND gate with 2 inputs per channel
• Electrical specifications: 4.5V ~ 5.5V supply voltage, 1mA/20mA output current, 0.8V/2V input logic levels, 5.6ns maximum propagation delay
• Package type: 14-SOIC surface mount configuration
• Thermal and environmental ratings: 0°C ~ 70°C operating temperature range
• Compliance certifications: ROHS3 compliance and MSL Level 1

The SN74F08DR qualifies as a direct substitute based on identical electrical and functional parameters. The primary distinction is packaging format: SN74F08DRG4 is supplied in tube packaging, while SN74F08DR is supplied in tape and reel format. Both components share the same base product number (74F08) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The SN74F08DR is the appropriate substitute for the SN74F08DRG4 based on the following factors:

• Identical electrical and functional specifications across all critical parameters
• Active product status ensures ongoing availability and supply chain continuity
• Both components maintain ROHS3 compliance and MSL Level 1 certification
• Equivalent performance in digital logic applications requiring 4-channel AND gate functionality
• The packaging format difference (tape and reel versus tube) does not affect functional compatibility; selection depends on assembly process requirements and quantity needs

Frequently Asked Questions (FAQ)

Q: Can SN74F08DR be used as a direct replacement for SN74F08DRG4 in existing designs?

A: Yes. Both components are electrically and functionally identical. The SN74F08DR operates within the same voltage range, provides identical propagation delay characteristics, and maintains the same input/output logic levels. The only difference is the packaging format.

Q: What is the difference between tube and tape & reel packaging?

A: Tube packaging (SN74F08DRG4) is typically used for smaller quantities and manual assembly processes. Tape and reel packaging (SN74F08DR) is designed for automated pick-and-place assembly equipment. Both formats contain the same component with identical electrical specifications.

Q: Why is the SN74F08DRG4 listed as discontinued?

A: The SN74F08DRG4 is discontinued at DiGi Electronics, but the functionally equivalent SN74F08DR remains in active production. This is a common occurrence where manufacturers consolidate product lines while maintaining the same logic function across different packaging formats.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components are ROHS3 compliant and carry MSL Level 1 certification. They meet identical environmental and regulatory requirements.

Q: What should I consider when selecting between these substitutes?

A: Consider your assembly process requirements. If your production uses automated equipment, the tape and reel format (SN74F08DR) is appropriate. If manual assembly or smaller quantities are involved, verify packaging availability. Both components deliver identical performance in 14-SOIC surface mount applications.
