Engineering Selection Recommendations

For Direct Replacement (Same Voltage Domain): The 74FCT163245CPAG from Renesas Electronics Corporation is the primary direct substitute. Both parts maintain identical electrical specifications (2.7V ~ 3.6V supply, 8mA/24mA output current) and functional characteristics. The difference is packaging form factor: 48-TSSOP versus 48-BSSOP. This part carries Last Time Buy status, indicating limited future availability.

For Higher Voltage Applications (4.5V ~ 5.5V Domain): When circuit topology permits operation at 5V supply levels, the following active parts provide long-term availability:

CY74FCT162H245CTPVC (Cypress Semiconductor Corp, Active status, 8365 Pcs inventory)
CY74FCT162245TPVCT (Cypress Semiconductor Corp, Active status, 7645 Pcs inventory)
CY74FCT162245TPVC (National Semiconductor, Active status, 1389 Pcs inventory)
CY74FCT162245ATPVC (Cypress Semiconductor Corp, Active status, 1217 Pcs inventory)

These parts maintain identical functional architecture (2 elements, 8 bits per element, 3-state output, 48-BSSOP package) with output current specifications of 24mA/24mA, suitable for standard 5V logic applications.

Compliance Considerations: All listed substitutes maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 74FCT163245CPVG be directly replaced with a 4.5V ~ 5.5V supply variant?

A: Direct replacement depends on circuit design. If the application operates exclusively in the 2.7V ~ 3.6V domain with no 5V interface requirements, higher voltage variants are not suitable. If the circuit includes 5V logic interfaces or operates from a 5V supply with proper level translation, 4.5V ~ 5.5V variants are functionally compatible. Verify supply voltage and interface requirements before substitution.

Q: What is the difference between 48-BSSOP and 48-TSSOP packaging?

A: Both are 48-pin surface mount packages with identical pin assignments and electrical performance. The primary difference is physical dimensions: 48-BSSOP has a 0.295" width (7.50mm), while 48-TSSOP has a 0.240" width (6.10mm). PCB layout and footprint design must accommodate the selected package variant. Verify footprint compatibility before design implementation.

Q: Why are some substitutes listed as Obsolete?

A: Obsolete parts have reached end-of-life status and are no longer manufactured. Existing inventory may be available through distributors, but long-term supply cannot be guaranteed. For new designs or production planning, prioritize Active status parts to ensure sustained availability.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitutes maintain ROHS3 compliance as specified in the provided data. This ensures compatibility with environmental regulations and modern manufacturing standards.

Q: What output current specifications should I consider for substitution?

A: The original 74FCT163245CPVG provides 8mA high and 24mA low output current. Higher voltage variants typically provide 24mA/24mA or 32mA/64mA. Higher output current capability is generally compatible with designs expecting lower current, provided the receiving logic can tolerate the increased drive strength. Verify load impedance and signal integrity requirements for your specific application.

Q: Can I use CY74FCT162245TPVCT as a direct substitute?

A: CY74FCT162245TPVCT is functionally equivalent but operates at 4.5V ~ 5.5V supply voltage. It is suitable only if your circuit operates in the 5V domain. It maintains identical pin configuration, 3-state output capability, and 48-BSSOP package form factor. Verify supply voltage compatibility before implementation.
