Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN74F08DRE4 is determined by the following critical parameters:

• Logic function: AND gate with 4 channels and 2 inputs per channel
• Electrical specifications: 4.5V ~ 5.5V supply voltage, 1mA/20mA output current, 5.6ns propagation delay
• Package type: 14-SOIC surface mount configuration
• Compliance: ROHS3 compliant, MSL Level 1

The SN74F08DR qualifies as a parametric equivalent based on identical electrical characteristics and package specifications. The primary distinction is packaging format: the SN74F08DRE4 is supplied in tube packaging, while the SN74F08DR is supplied in Tape & Reel (TR) format. Both parts share the same base product number (74F08) and maintain full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The SN74F08DR is the direct substitute for the SN74F08DRE4. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters. The SN74F08DR holds active product status, ensuring continued availability and supply chain reliability compared to the discontinued SN74F08DRE4.

Selection between these parts depends on packaging requirements and procurement volume. The SN74F08DRE4 tube packaging suits lower-volume applications and manual assembly processes. The SN74F08DR Tape & Reel format is optimized for automated pick-and-place assembly and higher-volume production runs. Both parts carry ROHS3 compliance and MSL Level 1 rating, meeting environmental and moisture sensitivity requirements for standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the SN74F08DR directly replace the SN74F08DRE4 in existing designs?
