Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74F32DG4 are qualified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Parameters (Must Match):

• Logic Type: OR Gate
• Number of Circuits: 4
• Number of Inputs: 2
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output High, Low: 1mA, 20mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ 5V: 5.6ns
• Operating Temperature: 0°C ~ 70°C

Mechanical Parameters (Must Match):

• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Supplier Device Package: 14-SOIC

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The primary difference between substitute parts lies in packaging format (Tube vs. Tape & Reel) and product status (Last Time Buy vs. Active).

Engineering Selection Recommendations

SN74F32DR (Recommended Primary Substitute)

The SN74F32DR is the manufacturer-recommended substitute for the SN74F32DG4. This part number maintains identical electrical and mechanical specifications while offering the advantage of Active product status from Texas Instruments. The SN74F32DR is supplied in Tape & Reel (TR) packaging format, which is standard for high-volume production environments. This part number provides the longest supply chain availability and is suitable for new designs and production volume requirements.

SN74F32D (Secondary Substitute)

The SN74F32D provides functional equivalence to the SN74F32DG4 with identical electrical and mechanical parameters. This part is supplied in Tube packaging format, matching the original SN74F32DG4 packaging type. However, the SN74F32D carries Last Time Buy status, indicating limited future availability. This part is suitable for low-volume applications, prototype builds, or situations where Tube packaging is specifically required.

Frequently Asked Questions (FAQ)

Q: Can SN74F32DR be used as a direct replacement for SN74F32DG4?

A: Yes. The SN74F32DR is electrically and mechanically equivalent to the SN74F32DG4. Both parts implement identical 4-channel 2-input OR gate logic with the same electrical characteristics, operating temperature range, and 14-SOIC package dimensions. The primary difference is packaging format (Tape & Reel vs. Tube) and product status (Active vs. Last Time Buy).

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies components in plastic tubes, typically used for lower-volume orders and manual assembly. Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly equipment. Both packaging formats contain identical components with the same electrical specifications.

Q: Are all three part numbers pin-compatible?

A: Yes. The SN74F32DG4, SN74F32DR, and SN74F32D all use the 14-SOIC package with identical pin assignments and pinout configurations. No circuit board modifications are required when substituting between these part numbers.

Q: Which substitute should I select for a new production design?

A: The SN74F32DR is the recommended choice for new production designs. This part carries Active product status from Texas Instruments, ensuring long-term supply chain availability and support. The Tape & Reel packaging format is optimized for automated assembly processes used in production environments.

Q: Can I use SN74F32D if SN74F32DR is unavailable?

A: Yes. The SN74F32D is electrically and mechanically equivalent and can serve as a substitute. However, verify that Tube packaging is compatible with your assembly process, as this format is typically used for lower-volume applications rather than production runs.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three part numbers are ROHS3 Compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited), ensuring compliance with environmental and regulatory standards across all substitute options.
