Key Parameters

Substitute Part Grouping Explanation

Substitute components for the PI3C3245QEX are qualified based on the following criteria:

Electrical Parameters: All substitute parts maintain identical circuit configuration (8 x 1:1), single supply voltage range (2.3V ~ 3.6V), and operating temperature range (-40°C ~ 85°C).

Mechanical Parameters: All substitute parts use the 20-SSOP package with 0.154" width (3.90mm), ensuring pin-compatible footprint compatibility.

Compliance Parameters: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements equivalent to the original component.

Product Status Consideration: Substitute parts from Texas Instruments (SN74CB3Q3245DBQR, SN74CB3Q3345DBQR, SN74CB3T3245DBQR, SN74CBTLV3245ADBQR) are in Active production status, providing long-term supply availability compared to the Last Time Buy status of the PI3C3245QEX.

Parameter Comparison

Engineering Selection Recommendations

All four Texas Instruments substitute parts (SN74CB3Q3245DBQR, SN74CB3Q3345DBQR, SN74CB3T3245DBQR, SN74CBTLV3245ADBQR) are direct functional equivalents to the PI3C3245QEX. Selection among these options should prioritize Active product status for long-term supply assurance. The SN74CBTLV3245ADBQR offers the highest current inventory level (23,459 pcs), supporting immediate procurement needs. All candidates maintain identical electrical specifications, package compatibility, and regulatory compliance (ROHS3, REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Are all substitute parts pin-compatible with the PI3C3245QEX?

A: Yes. All substitute parts use the 20-SSOP package with identical 0.154" (3.90mm) width, ensuring direct footprint compatibility without PCB redesign.

Q: What is the primary reason to substitute the PI3C3245QEX?

A: The PI3C3245QEX is in Last Time Buy status, indicating discontinued production. Texas Instruments substitutes are in Active production, ensuring long-term supply availability.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All substitute parts are ROHS3 compliant and REACH Unaffected, matching the compliance profile of the original component.

Q: Are there electrical differences between the substitute options?

A: No. All substitute parts maintain identical voltage supply range (2.3V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and 8 x 1:1 circuit configuration.

Q: Which substitute part should be selected for new designs?

A: Any of the four Texas Instruments options are suitable. Selection may be based on packaging preference (Tape & Reel vs. Cut Tape) or inventory availability. The SN74CBTLV3245ADBQR provides the highest stock level.

Q: Is there a difference between the 74CB3Q, 74CB3T, and 74CBTLV series designations?

A: These designations reflect Texas Instruments product line classifications. All maintain equivalent electrical and mechanical specifications for bus switch functionality within the specified voltage and temperature ranges.
