Substitute Part Grouping Explanation

Substitution of the SN74F32NG4 is determined by strict equivalence across the following critical parameters:

  • Logic Type: OR Gate with 4 channels and 2 inputs per channel
  • Voltage Supply Range: 4.5V ~ 5.5V
  • Output Current Specifications: 1mA high, 20mA low
  • Input Logic Levels: 0.8V low threshold, 2V high threshold
  • Propagation Delay: 5.6ns @ 5V
  • Operating Temperature Range: 0°C ~ 70°C
  • Package Configuration: 14-DIP through-hole mounting
  • Series Classification: 74F logic family
  • Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

Only parts matching all these parameters across the 74F series are considered direct substitutes. Package type and mounting method must remain identical to ensure mechanical and electrical compatibility in existing PCB designs.

Engineering Selection Recommendations

The SN74F32N is a direct functional equivalent to the SN74F32NG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, logic configuration, and package dimensions. The primary distinction is product status: the SN74F32NG4 is discontinued at DiGi Electronics, while the SN74F32N maintains active status with higher inventory availability (3400 pcs vs. 1097 pcs).

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The SN74F32N is supplied in tube packaging, which is standard for active production components. Electrical performance, including propagation delay, output current, and input logic thresholds, is identical between both parts.

Selection of the SN74F32N is appropriate for new designs and production runs where component continuity and long-term availability are required.

Frequently Asked Questions (FAQ)
