PI5C3244SE Equivalent & Substitute Parts

Part Overview

The PI5C3244SE is a bus switch IC manufactured by Diodes Incorporated, designed for 4 x 1:1 switching applications in logic circuits. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The PI5C3244SE operates as a single-supply bus switch with 2 independent circuits in a 20-SOIC surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI5C3244SE are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Substitution Criteria:

• Circuit configuration: 4 x 1:1 bus switch topology
• Independent circuits: 2
• Package type: 20-SOIC (0.295", 7.50mm Width)
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 85°C
• Voltage supply source: Single Supply
• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts identified are from Texas Instruments' 74CBT series, which maintain identical circuit architecture, package specifications, and environmental operating parameters. Variations in supply voltage range and product status reflect different manufacturing generations and availability conditions.

Parameter Comparison

Engineering Selection Recommendations

For Active Production: SN74CBT3244CDW and SN74CBT3244CDWR are the primary substitutes, both carrying Active product status from Texas Instruments. These parts maintain full compatibility with the PI5C3244SE across all critical electrical and mechanical parameters. The SN74CBT3244CDWR variant in Tape & Reel packaging is suitable for high-volume automated assembly operations, while the SN74CBT3244CDW in Tube packaging accommodates lower-volume or manual assembly processes.

For Legacy Support: SN74CBT3244DW and SN74CBT3244DWR carry Last Time Buy status, indicating limited future availability. These parts remain functionally equivalent but should be considered only when Active alternatives are unavailable or when existing inventory must be consumed.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the original PI5C3244SE specifications. No additional handling or storage requirements are introduced through substitution.

Frequently Asked Questions (FAQ)

Q: Can SN74CBT3244CDW directly replace PI5C3244SE in existing designs? A: Yes. Both parts share identical circuit configuration (4 x 1:1), independent circuit count (2), package type (20-SOIC), and operating temperature range (-40°C ~ 85°C). Pin-for-pin compatibility is maintained.

Q: What is the difference between SN74CBT3244CDW and SN74CBT3244CDWR? A: The primary difference is packaging format. SN74CBT3244CDW is supplied in Tube packaging, while SN74CBT3244CDWR is supplied in Tape & Reel (TR) format. Electrical specifications and performance are identical. Tape & Reel packaging is standard for automated pick-and-place assembly, while Tube packaging is typical for manual or lower-volume handling.

Q: Why does the PI5C3244SE show as Obsolete? A: The PI5C3244SE is no longer manufactured by Diodes Incorporated. Texas Instruments' 74CBT3244 series provides functionally equivalent alternatives with active manufacturing support.

Q: Are there voltage supply differences between the PI5C3244SE and substitute parts? A: The PI5C3244SE operates at 4.75V ~ 5.25V, while SN74CBT3244CDW and SN74CBT3244CDWR support 4V ~ 5.5V. The substitute parts accept a wider voltage range, ensuring compatibility with the original specification and providing additional operational margin.

Q: What is the significance of Last Time Buy status for SN74CBT3244DW and SN74CBT3244DWR? A: Last Time Buy status indicates these parts will no longer be manufactured after a specified date. Existing inventory may be available, but future procurement should prioritize Active status parts (SN74CBT3244CDW or SN74CBT3244CDWR) for long-term design continuity.

Q: Do all substitute parts maintain the same Moisture Sensitivity Level? A: Yes. All substitute parts maintain Moisture Sensitivity Level 1 (Unlimited), matching the PI5C3244SE. No additional moisture control measures are required during storage or handling.
