PI5C3384S Equivalent & Substitute Parts

Part Overview

The PI5C3384S is a bus switch IC manufactured by Diodes Incorporated, designed for 5 x 1:1 switching applications in 20-SOIC packaging. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The PI5C3384S operates as a single-supply logic device with a voltage range of 4.75V to 5.25V and supports operating temperatures from -40°C to 85°C. Due to its obsolete status, equivalent parts from active product lines are required to maintain design continuity and ensure component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI5C3384S is based on functional equivalence within the allowed electrical and mechanical parameters. The substitute parts are Texas Instruments SN74CBT3384 series components, which maintain the core functional specification of a 5 x 1:1 bus switch with 2 independent circuits and single-supply operation.

The key parameters determining substitution validity are:

• Circuit configuration: 5 x 1:1 topology with 2 independent circuits
• Voltage supply source: Single supply operation
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface mount
• Logic category: Bus switch functionality

The substitute parts operate within a slightly wider voltage supply range (4.5V ~ 5.5V) compared to the original PI5C3384S (4.75V ~ 5.25V), providing enhanced compatibility. All substitute parts are packaged in 24-SOIC format, which differs from the original 20-SOIC package. This package change requires PCB layout modification but maintains electrical equivalence for the switching function.

Engineering Selection Recommendations

For new designs and production continuity, SN74CBT3384CDWR is the primary recommended substitute. This part carries Active product status from Texas Instruments, ensuring long-term availability and supply chain stability. It is ROHS3 compliant, meeting current environmental and regulatory requirements that the obsolete PI5C3384S does not satisfy.

SN74CBT3384ADW and SN74CBT3384ADWR are secondary options with Last Time Buy status, indicating limited future availability. These parts remain suitable for legacy system maintenance but should not be selected for new production designs requiring extended component lifecycles.

All three substitute parts require PCB layout modification due to the package transition from 20-SOIC to 24-SOIC. The electrical functionality remains equivalent within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can SN74CBT3384 series parts directly replace PI5C3384S without PCB modification?

A: No. The PI5C3384S uses 20-SOIC packaging while all SN74CBT3384 substitutes use 24-SOIC packaging. PCB footprint redesign is required. The electrical function is equivalent, but physical layout changes are mandatory.

Q: What is the difference between SN74CBT3384ADW, SN74CBT3384ADWR, and SN74CBT3384CDWR?

A: The primary difference is packaging format and product status. SN74CBT3384ADW is supplied in Tube packaging with Last Time Buy status. SN74CBT3384ADWR is supplied in Cut Tape format with Last Time Buy status. SN74CBT3384CDWR is supplied in Tape & Reel format with Active product status. All three are electrically equivalent 24-SOIC devices.

Q: Is the wider voltage supply range of SN74CBT3384 (4.5V ~ 5.5V) compatible with PI5C3384S designs (4.75V ~ 5.25V)?

A: Yes. The SN74CBT3384 voltage range encompasses the PI5C3384S range. Designs operating within 4.75V to 5.25V will function correctly with the substitute part.

Q: Why is SN74CBT3384CDWR recommended over the other two substitutes?

A: SN74CBT3384CDWR has Active product status, ensuring continued manufacturing and availability. The other two parts have Last Time Buy status, indicating limited future supply. For production designs requiring component availability beyond the Last Time Buy window, SN74CBT3384CDWR is the appropriate choice.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three SN74CBT3384 substitutes are ROHS3 compliant, whereas the original PI5C3384S is RoHS non-compliant. This compliance improvement is a benefit of transitioning to the substitute parts.

Q: What is the moisture sensitivity level for the substitute parts?

A: All substitute parts maintain MSL 1 (Unlimited), identical to the original PI5C3384S. No additional moisture control measures are required during handling or storage.
