Engineering Selection Recommendations
For new designs and ongoing production, 74ACT16245DLR is the primary recommended substitute. This part is manufactured by Texas Instruments with Active product status, ensuring long-term availability and supply continuity. It maintains identical electrical specifications and package configuration while offering superior lifecycle support compared to the Last Time Buy 74ACT16245DL.
For applications where Texas Instruments sourcing is constrained, 74FCT162H245CTPVC from Cypress Semiconductor Corp provides an Active alternative with equivalent parametric specifications. This part maintains the same 48-BSSOP package, voltage supply range, operating temperature, and output current ratings.
Parts with Obsolete status (74FCT162245ATPVG, 74FCT162H245ATPVC, CY74FCT162245CTPVC) should be considered only for legacy system maintenance where supply exists and no design refresh is planned. These parts carry higher procurement risk due to discontinued manufacturing status.
All substitute parts listed comply with ROHS3 requirements where specified, supporting environmental and regulatory compliance objectives.
Frequently Asked Questions (FAQ)
Q: Can 74ACT16245DLR be used as a direct replacement for 74ACT16245DL?
A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, operating temperature range, supply voltage, output current ratings, and 48-BSSOP package configuration. The primary difference is product status: 74ACT16245DLR is Active, while 74ACT16245DL is Last Time Buy. 74ACT16245DLR is the recommended long-term substitute.
Q: What is the difference between 74ACT and 74FCT series parts?
A: Both series provide non-inverting transceiver functionality with identical electrical parameters for this application. The 74ACT series is manufactured by Texas Instruments, while 74FCT variants are available from multiple manufacturers including Renesas Electronics Corporation and Cypress Semiconductor Corp. All maintain the same 2-element, 8-bit configuration with 3-state output and 48-BSSOP packaging.
Q: Are all substitute parts pin-compatible with 74ACT16245DL?
A: Yes. All listed substitute parts use the 48-BSSOP package with identical pinout, enabling direct PCB-level replacement without layout modifications.
Q: What does Moisture Sensitivity Level (MSL) 1 mean?
A: MSL 1 indicates unlimited shelf life without moisture baking requirements. Parts with MSL 3 require moisture baking after extended storage. The 74ACT16245DL and most recommended substitutes carry MSL 1 rating.
Q: Should I avoid parts with Obsolete status?
A: Obsolete parts carry supply risk and should be avoided for new designs. They are suitable only for legacy system maintenance where existing inventory is available. For new production, select from Active status parts: 74ACT16245DLR, CY74FCT162245TPVC, 74FCT162H245CTPVC, or CY74FCT162245ATPVC.
Q: Are RoHS3 certifications required for my application?
A: RoHS3 compliance is mandatory for products sold in the European Union and many other markets. The 74ACT16245DL, 74ACT16245DLR, 74ACT16623DL, 74FCT162245ATPVG, 74FCT162H245ATPVC, and CY74FCT162245CTPVC all carry ROHS3 Compliant status. Verify your application requirements before selecting parts without explicit RoHS certification.
