PI5C3384LE Equivalent & Substitute Parts
Part Overview
The PI5C3384LE is a Bus Switch 5 x 1:1 logic IC manufactured by Diodes Incorporated in 24-TSSOP packaging. This component functions as a multiplexer for digital signal routing with five independent 1:1 switching circuits. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical circuit topology, voltage specifications, and package compatibility to ensure direct replacement capability.

Substitute Part Grouping Explanation
Substitution eligibility for the PI5C3384LE is determined by the following critical parameters:
- Circuit topology: 5 x 1:1 configuration with 2 independent circuits
- Voltage supply range compatibility: Parts must operate within overlapping supply voltage windows
- Package type: 24-pin surface mount packages (TSSOP or QSOP variants)
- Operating temperature range: -40°C to 85°C minimum
- RoHS3 compliance and MSL rating of 1
Substitute parts are grouped into two categories based on package type: 24-TSSOP (direct footprint replacement) and 24-QSOP (alternative package with different physical dimensions but identical electrical function).

Engineering Selection Recommendations
For direct footprint replacement in existing PCB designs, select from the 24-TSSOP package variants: CBTD3384PW,118 (Nexperia), CBT3384PW,118 (NXP), or SN74CBT3384CPWR (Texas Instruments). These parts maintain identical package dimensions and pin assignments to the PI5C3384LE.
The SN74CBT3384CPWR offers the highest inventory availability (6,200 units) and active product status, making it the primary recommendation for new production. The CBT3384PW,118 from NXP provides an alternative with comparable availability (9,893 units).
For applications where package footprint modification is acceptable, the QS3384QG8 from Renesas Electronics provides an active product alternative with identical electrical specifications. This part uses a 24-QSOP package (0.154" width versus 0.173" for TSSOP), requiring PCB layout adjustment.
All recommended substitutes maintain ROHS3 compliance, MSL rating of 1, and operating temperature range compatibility with the original PI5C3384LE.
Frequently Asked Questions (FAQ)
Q: Can I use QS3384QG8 as a direct replacement for PI5C3384LE on my existing PCB?
A: No. The QS3384QG8 uses 24-QSOP packaging (0.154" width) while PI5C3384LE uses 24-TSSOP packaging (0.173" width). Physical footprint and pin spacing differ, requiring PCB redesign. Use 24-TSSOP variants for direct replacement.
Q: What is the voltage supply difference between PI5C3384LE and substitute parts?
A: PI5C3384LE operates at 4.75V ~ 5.25V. Most substitutes (CBTD3384PW,118, CBT3384PW,118, and Texas Instruments variants) operate at 4.5V ~ 5.5V, providing wider supply range compatibility. QS3384QG8 matches the original 4.75V ~ 5.25V specification.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), matching the environmental and reliability standards of the original PI5C3384LE.
Q: Which substitute has the best long-term availability?
A: SN74CBT3384CPWR (Texas Instruments) carries Active product status with 6,200 units in stock, providing the most stable long-term availability. CBT3384PW,118 (NXP) is also Active with 9,893 units available.
Q: Do all substitutes maintain the same circuit configuration?
A: Yes. All substitute parts maintain the 5 x 1:1 circuit topology with 2 independent circuits and identical operating temperature range (-40°C ~ 85°C) as the PI5C3384LE.
