PI5C3244S Equivalent & Substitute Parts

Part Overview

The PI5C3244S is a bus switch IC manufactured by Diodes Incorporated, configured as a 4 x 1:1 logic switch in a 20-SOIC package. This component functions as a multiplexer for digital signal routing in single-supply applications. The part is currently obsolete, making equivalent substitutes necessary for ongoing system support and new designs requiring this functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI5C3244S is determined by the following critical parameters:

• Circuit configuration: 4 x 1:1 topology with 2 independent circuits
• Package type: 20-SOIC form factor with identical physical dimensions
• Voltage supply range: Single supply operation within compatible voltage windows
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface mount technology

The Texas Instruments SN74CBT3244 series satisfies these core requirements. All substitute parts maintain the identical 4 x 1:1 circuit configuration, 20-SOIC package, and operating temperature range. Voltage supply ranges vary slightly across packaging options but remain compatible with standard 5V logic applications.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing system support, the SN74CBT3244CDW and SN74CBT3244CDWR are the primary substitutes. Both parts carry Active product status and ROHS3 compliance, providing long-term availability and regulatory alignment. The SN74CBT3244CDW is supplied in Tube packaging, while the SN74CBT3244CDWR is supplied in Tape & Reel format for automated assembly processes.

The SN74CBT3244DW and SN74CBT3244DWR are available as Last Time Buy options. These parts maintain full functional and electrical equivalence but have limited future availability. Selection between these variants depends on production volume and packaging requirements.

All substitute parts operate within the temperature range of the original PI5C3244S. Voltage supply ranges for the SN74CBT3244 series encompass the original specification, ensuring compatibility with existing power supply designs.

Frequently Asked Questions (FAQ)

Q: Can SN74CBT3244 series parts directly replace the PI5C3244S in existing designs?

A: Yes. All substitute parts maintain identical circuit configuration (4 x 1:1), package type (20-SOIC), and operating temperature range (-40°C ~ 85°C). Pin-to-pin compatibility is preserved across all variants.

Q: What is the difference between tube and tape & reel packaging options?

A: Tube packaging (CDW, DW variants) is suitable for manual assembly and lower-volume applications. Tape & Reel packaging (CDWR, DWR variants) is designed for automated pick-and-place assembly processes and higher production volumes.

Q: Are there voltage supply differences between substitute options?

A: The SN74CBT3244CDW and SN74CBT3244CDWR support 4V ~ 5.5V operation. The SN74CBT3244DW and SN74CBT3244DWR support 4.5V ~ 5.5V operation. Both ranges encompass the original PI5C3244S specification of 4.75V ~ 5.25V.

Q: What is the significance of product status differences?

A: Active status (CDW, CDWR) indicates ongoing production and long-term availability. Last Time Buy status (DW, DWR) indicates limited future production with defined end-of-life dates. For new designs, Active status parts are recommended.

Q: Does RoHS compliance affect functional compatibility?

A: No. RoHS compliance is a manufacturing and environmental standard that does not alter electrical or functional characteristics. The ROHS3-compliant SN74CBT3244 variants are functionally equivalent to the non-compliant PI5C3244S.
