74F32SJX OR Gate IC Equivalent & Substitute Parts

Part Overview

The 74F32SJX is a 4-channel 2-input OR gate logic IC manufactured by onsemi in a 14-SOP surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 74F32 series maintains consistent functional and electrical characteristics across manufacturers, enabling direct substitution based on matching electrical parameters and package compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74F32SJX is determined by matching the following critical parameters: logic function (4-channel 2-input OR gate), 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), operating temperature range (0°C ~ 70°C), and surface mount packaging. All identified substitute parts maintain these electrical and functional specifications. Package variations (14-SOP, 14-SO, 14-SOIC) are mechanically compatible within standard PCB assembly processes for surface mount components.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, SN74F32DR (Texas Instruments) is the primary substitute. This part maintains active product status, ROHS3 compliance, and identical electrical specifications to the 74F32SJX. The 14-SOIC package (0.154" width) is standard for modern surface mount assembly processes.

SN74F32NSR (Texas Instruments) provides an alternative with active status and ROHS3 compliance, packaged in 14-SO format with Tape & Reel delivery.

SN74F32D (Texas Instruments) is available but classified as Last Time Buy, indicating limited future availability. This part is suitable only for legacy system maintenance where existing inventory or procurement channels are established.

All three Texas Instruments substitutes provide ROHS3 compliance, addressing regulatory requirements beyond the obsolete onsemi part.

Frequently Asked Questions (FAQ)

Q: Can SN74F32DR directly replace 74F32SJX in existing designs? A: Yes. Both parts maintain identical electrical specifications: 4-channel 2-input OR gate function, 4.5V ~ 5.5V supply, 1mA/20mA output current, 0.8V/2V input thresholds, and 5.6ns propagation delay at 5V. Surface mount package compatibility is confirmed for standard PCB assembly.

Q: What is the difference between 14-SOP, 14-SO, and 14-SOIC packages? A: These are surface mount outline variations of the same 14-pin configuration. 14-SOP (Small Outline Package) and 14-SO are functionally equivalent. 14-SOIC (Small Outline Integrated Circuit) variants differ in body width: 0.209" (5.30mm) versus 0.154" (3.90mm). Pin pitch and electrical function remain consistent. PCB footprint design must match the specific package selected.

Q: Why is 74F32SJX classified as obsolete? A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. Texas Instruments continues active production of equivalent 74F32 variants, ensuring long-term design support and component availability.

Q: Are all substitutes ROHS3 compliant? A: Yes. All Texas Instruments substitutes (SN74F32NSR, SN74F32D, SN74F32DR) carry ROHS3 compliance certification. The original 74F32SJX is REACH Unaffected but does not carry ROHS3 designation.

Q: What is the difference between Tape & Reel and Tube packaging? A: Tape & Reel (TR) packaging is optimized for automated assembly lines with continuous component feeding. Tube packaging is suitable for manual assembly or lower-volume applications. Electrical and functional specifications are identical; packaging choice depends on assembly process requirements.
