Parameter Comparison

Engineering Selection Recommendations

SN74CB3Q16244DGGR (Texas Instruments) is the primary substitute option. This part maintains full electrical and mechanical compatibility with the PI3B16244AEX while offering an extended lower voltage supply range (2.3V minimum versus 3V). The device is active in production with ROHS3 compliance and MSL 1 rating, ensuring long-term availability and regulatory compliance.

QS3VH16244PAG and QS3VH16244PAG8 (IDT) are alternative substitutes from Integrated Device Technology Inc. Both variants provide identical circuit configuration and package specifications. The QS3VH16244PAG8 variant offers higher inventory availability. These parts operate within the same temperature range and package footprint, with extended lower voltage supply capability (2.3V minimum).

Selection between substitute parts should be based on:

• Availability requirements and lead times
• Packaging preferences (Cut Tape vs. Bulk)
• Supply chain qualification status
• Inventory levels for production volume needs

Frequently Asked Questions (FAQ)

Q: Can SN74CB3Q16244DGGR directly replace PI3B16244AEX in existing designs?

A: Yes. Both parts share identical circuit configuration (4 x 1:1), package type (48-TFSOP), and operating temperature range (-40°C ~ 85°C). The SN74CB3Q16244DGGR supports a lower minimum supply voltage (2.3V vs. 3V), making it functionally compatible for applications operating at 3V ~ 3.6V.

Q: What is the difference between QS3VH16244PAG and QS3VH16244PAG8?

A: Both parts are functionally identical with the same circuit configuration, voltage specifications, and package type. The primary difference is packaging format and inventory availability. QS3VH16244PAG8 has significantly higher stock levels (12,445 pcs vs. 3,691 pcs).

Q: Are all substitute parts RoHS compliant?

A: SN74CB3Q16244DGGR is explicitly ROHS3 compliant. RoHS compliance status for QS3VH16244PAG and QS3VH16244PAG8 is not specified in the provided data.

Q: Do substitute parts require PCB layout modifications?

A: No. All substitute parts use the identical 48-TFSOP package with 0.240" (6.10mm) width, requiring no PCB footprint changes.

Q: What is the moisture sensitivity level for IDT parts?

A: MSL ratings for QS3VH16244PAG and QS3VH16244PAG8 are not specified in the provided documentation.
