PI5C3384LEX Equivalent & Substitute Parts

Part Overview

The PI5C3384LEX is a bus switch IC manufactured by Diodes Incorporated, featuring a 5 x 1:1 circuit configuration in a 24-TSSOP package. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part operates under single supply voltage conditions with a supply range of 4.75V to 5.25V and supports operating temperatures from -40°C to 85°C. Equivalent and substitute parts maintain the same functional circuit topology and package footprint compatibility while offering active product status from alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI5C3384LEX is determined by the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration: 5 x 1:1 topology with 2 independent circuits
• Package type: 24-TSSOP surface mount package
• Voltage supply source: Single supply operation
• Operating temperature range: -40°C to 85°C minimum
• RoHS3 compliance and MSL Level 1 rating

Substitution Groups:

Group 1: Direct 24-TSSOP Package Equivalents Parts maintaining identical 24-TSSOP package footprint with compatible voltage supply ranges (4.5V ~ 5.5V or 4.75V ~ 5.25V):

• SN74CBTD3384CPWR (Texas Instruments, 4.5V ~ 5.5V supply)
• SN74CBT3384CPWR (Texas Instruments, 4.5V ~ 5.5V supply)
• SN74CBT3384APW (Texas Instruments, 4.5V ~ 5.5V supply)
• SN74CBT3384APWR (Texas Instruments, 4.5V ~ 5.5V supply)
• SN74CBT3384CPW (Texas Instruments, 4.5V ~ 5.5V supply)
• CBT3384PW,118 (NXP Semiconductors, 4.5V ~ 5.5V supply)

Group 2: Alternative Package Equivalents Parts with identical circuit configuration and electrical specifications but different package types:

• QS3384QG (Renesas Electronics, 24-QSOP package, 4.75V ~ 5.25V supply)
• QS3384QG8 (Renesas Electronics, 24-QSOP package, 4.75V ~ 5.25V supply)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same PCB Footprint): Select from Texas Instruments 24-TSSOP variants with active product status: SN74CBTD3384CPWR or SN74CBT3384CPWR. Both maintain identical package dimensions and pin configuration. The SN74CBTD3384CPWR offers extended voltage supply range (4.5V ~ 5.5V) compared to the original specification (4.75V ~ 5.25V), providing additional design margin. Both parts carry ROHS3 compliance and MSL Level 1 rating.

For Long-Term Availability: SN74CBT3384CPWR from Texas Instruments is recommended due to active product status and established supply chain presence. This part is suitable for new production designs requiring sustained component availability.

For Voltage Supply Compatibility: If the design operates strictly within 4.75V ~ 5.25V supply range, Renesas QS3384QG or QS3384QG8 variants maintain exact voltage specifications matching the original PI5C3384LEX. These parts require PCB layout modification due to 24-QSOP package dimensions (0.154", 3.90mm width versus 0.173", 4.40mm width for TSSOP).

Compliance Considerations: All recommended substitutes maintain ROHS3 compliance and MSL Level 1 rating. NXP CBT3384PW,118 requires verification of RoHS status prior to selection for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can I use QS3384QG or QS3384QG8 as direct PCB replacements for PI5C3384LEX?

A: No. While QS3384QG and QS3384QG8 maintain identical circuit configuration and electrical specifications, the 24-QSOP package (0.154", 3.90mm width) differs from the 24-TSSOP package (0.173", 4.40mm width). PCB layout modification is required, including footprint changes and potential trace routing adjustments.

Q: What is the voltage supply difference between PI5C3384LEX and Texas Instruments substitutes?

A: The PI5C3384LEX operates at 4.75V ~ 5.25V. Texas Instruments SN74CBT and SN74CBTD series parts operate at 4.5V ~ 5.5V, providing 0.25V additional margin on both supply rails. This extended range is compatible with designs using the original part and offers improved noise immunity.

Q: Are SN74CBT3384APW and SN74CBT3384APWR suitable for new production designs?

A: Both parts carry Last Time Buy status, indicating discontinued production. These parts are suitable only for legacy system support or existing inventory utilization. For new production designs, select SN74CBTD3384CPWR or SN74CBT3384CPWR with active product status.

Q: What is the difference between tape and reel (TR) and tube packaging?

A: Tape and reel packaging is suitable for automated assembly processes with high-volume production. Tube packaging is used for lower-volume applications or manual assembly. Both packaging types contain identical components; selection depends on manufacturing process requirements.

Q: Can I substitute PI5C3384LEX with CBT3384PW,118 from NXP?

A: CBT3384PW,118 maintains identical circuit configuration, package type, and operating specifications. However, RoHS compliance status is not specified in available documentation. Verification with NXP is required before selection for applications requiring documented RoHS3 compliance.

Q: What does MSL Level 1 mean for moisture sensitivity?

A: MSL Level 1 indicates unlimited shelf life without moisture baking requirements. Components with this rating can be stored indefinitely under normal conditions without special moisture control measures, simplifying inventory management and reducing production constraints.
