Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI5V330WE is determined by the following critical parameters:

• Package Compatibility: 16-SOIC form factor (0.154", 3.90mm Width) - all substitutes maintain identical package specifications
• Functional Equivalence: 2:1 multiplexer/demultiplexer circuit with 4 channels and 10Ω maximum on-state resistance
• Operating Temperature Range: -40°C ~ 85°C (TA) - all substitutes support this range
• RGB Feature Support: Bi-directional RGB capability required for video switching applications
• Supply Voltage Compatibility: The PI5V330WE operates at 5V single supply. Substitutes are grouped by supply voltage requirements:
  • 3V Group: TS3V330D and TS3V330DR (3V ~ 3.6V supply) - suitable for 3.3V systems
  • 5V Group: TS5V330D and TS5V330DR (4V ~ 5.5V supply) - suitable for 5V systems and backward compatible with PI5V330WE

All substitute parts maintain ROHS3 compliance, MSL Level 1, and identical mechanical mounting specifications.

Parameter Comparison

Engineering Selection Recommendations

For 5V System Applications: TS5V330D or TS5V330DR are the direct functional equivalents for the PI5V330WE. Both parts operate within the 4V ~ 5.5V supply range, maintaining compatibility with existing 5V designs. TS5V330DR offers higher inventory availability (16,085 pcs) compared to TS5V330D (1,726 pcs). Both parts are classified as Last Time Buy, indicating limited future availability.

For 3.3V System Applications: TS3V330D or TS3V330DR provide equivalent functionality within the 3V ~ 3.6V supply range. TS3V330DR is recommended due to higher inventory (4,459 pcs versus 1,313 pcs for TS3V330D) and active product status, ensuring longer-term component availability.

Bandwidth Consideration: The PI5V330WE specifies 400MHz bandwidth, while all Texas Instruments substitutes specify 300MHz. This represents a reduction in maximum bandwidth performance. Applications requiring the full 400MHz specification should evaluate whether 300MHz bandwidth meets system requirements.

Bi-Directional Feature: TS5V330D and TS5V330DR maintain the bi-directional feature of the original part. TS3V330D and TS3V330DR do not specify bi-directional capability; applications requiring this feature should select from the 5V group.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can TS3V330D or TS3V330DR be used as direct replacements for PI5V330WE in a 5V system?

A: No. The TS3V330D and TS3V330DR are specified for 3V ~ 3.6V supply operation. Using these parts in a 5V system exceeds their maximum supply voltage rating and will result in component failure or unpredictable behavior.

Q: What is the difference between TS5V330D and TS5V330DR?

A: Both parts are functionally identical with identical electrical specifications. The primary difference is packaging: TS5V330D is supplied in Tube packaging, while TS5V330DR is supplied in Cut Tape (CT) packaging. TS5V330DR has significantly higher inventory availability (16,085 pcs versus 1,726 pcs).

Q: Why do the Texas Instruments substitutes specify 300MHz bandwidth instead of 400MHz?

A: The bandwidth specification difference reflects the design characteristics of each manufacturer's implementation. Applications must evaluate whether 300MHz bandwidth is sufficient for their video switching requirements. The 100MHz reduction may impact high-frequency video signal integrity in bandwidth-critical applications.

Q: Are TS3V330D and TS3V330DR suitable for designs currently using PI5V330WE?

A: Only if the system design is modified to operate at 3.3V supply voltage. Direct substitution in existing 5V designs is not possible due to supply voltage incompatibility. TS5V330D or TS5V330DR are the appropriate substitutes for existing 5V designs.

Q: What is the significance of "Last Time Buy" status for TS5V330D and TS5V330DR?

A: Last Time Buy status indicates that Texas Instruments will discontinue these parts after a specified date. While currently available, long-term design support should consider TS3V330DR, which maintains Active product status and ensures extended availability.

Q: Do all substitute parts maintain the same 16-SOIC package dimensions?

A: Yes. All substitute parts use the 16-SOIC (0.154", 3.90mm Width) package, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Q: Are there supply voltage compatibility considerations when selecting between substitute parts?

A: Yes. The supply voltage range determines substitution eligibility: TS3V330D/TS3V330DR operate at 3V ~ 3.6V, while TS5V330D/TS5V330DR operate at 4V ~ 5.5V. Selection must match the system's supply voltage specification. The PI5V330WE operates at 5V, making the TS5V330 series the appropriate substitute for existing designs.
