Engineering Selection Recommendations
For Direct Replacement (Identical Electrical Specifications): Select from 74FCT162245ATPACT, 74FCT162245CTPACT, 74FCT162H245ATPACT, 74FCT162H245CTPACT, 74ACT16245DGGR, 74FCT162245ATPVG, 74FCT162245CTPAG, or 74FCT16245ATPAG. These parts maintain the 4.5V to 5.5V supply voltage range and 24mA output current specifications. Among these, 74FCT162245CTPAG and 74FCT16245ATPAG carry Active product status, providing superior long-term availability and supply chain stability compared to obsolete alternatives.
For Low-Power Applications: The SN74LVCR162245DGGR is suitable for systems operating at 3.3V or lower supply voltages with reduced power consumption requirements. This part operates at 2.7V to 3.6V with 12mA output current and carries Active product status. Selection of this part requires confirmation that the application's logic voltage levels and output drive requirements are compatible with the lower current specifications.
For Enhanced Output Drive: The 74FCT16245ATPAG provides increased output current capability (32mA high, 64mA low) while maintaining the 4.5V to 5.5V supply voltage range and 48-TFSOP package. This part is suitable for applications requiring higher fanout or longer trace lengths. Active product status ensures continued availability.
Compliance and Certification: All recommended substitute parts maintain ROHS3 compliance and operate across the -40°C to 85°C temperature range. Parts with MSL 1 rating (unlimited moisture sensitivity) provide superior handling flexibility during storage and assembly compared to MSL 3 rated alternatives.
Frequently Asked Questions (FAQ)
Q: Can the SN74LVCR162245DGGR directly replace the CY74FCT162245TPACT in a 5V system?
A: No. The SN74LVCR162245DGGR operates at 2.7V to 3.6V supply voltage, making it incompatible with 5V systems. Direct substitution requires a part maintaining the 4.5V to 5.5V supply range, such as 74FCT162245ATPACT or 74ACT16245DGGR.
Q: What is the difference between 74FCT162245ATPVG and 74FCT162245CTPAG?
A: Both parts maintain identical electrical specifications (4.5V to 5.5V supply, 24mA output current, 2 elements, 8 bits per element, 3-state output). The primary differences are packaging format (48-BSSOP versus 48-TFSOP) and moisture sensitivity level (MSL 3 versus MSL 1). The 48-TFSOP package of 74FCT162245CTPAG matches the original CY74FCT162245TPACT footprint more closely.
Q: Are all substitute parts pin-compatible with the CY74FCT162245TPACT?
A: All listed substitute parts share the same 48-pin TFSOP or BSSOP package footprint and maintain identical pin assignments for the transceiver logic function. However, 74FCT162245ATPVG uses a 48-BSSOP package (0.295" width) versus the 48-TFSOP package (0.240" width) of the original part, requiring PCB layout verification.
Q: Which substitute part offers the best long-term availability?
A: Parts with Active product status provide superior long-term availability. SN74LVCR162245DGGR, 74ACT16245DGGR, 74FCT162245CTPAG, and 74FCT16245ATPAG all carry Active status. Among these, 74FCT162245CTPAG and 74FCT16245ATPAG maintain the original 4.5V to 5.5V supply voltage specification.
Q: What is the significance of the 74FCT16245ATPAG having higher output current (32mA/64mA)?
A: The 74FCT16245ATPAG provides increased output drive capability, enabling it to drive longer PCB traces or higher fanout loads. This part is suitable for applications where the original 24mA specification may be marginal. All other electrical and functional parameters remain compatible with the CY74FCT162245TPACT.
Q: Are there any thermal or environmental differences between substitute parts?
A: All substitute parts operate across the identical -40°C to 85°C temperature range. Moisture sensitivity levels vary: parts with MSL 1 (CY74FCT162245TPACT, 74FCT162245ATPACT, 74FCT162245CTPACT, 74FCT162H245ATPACT, 74FCT162H245CTPACT, SN74LVCR162245DGGR, 74ACT16245DGGR) provide unlimited shelf life, while 74FCT162245ATPVG with MSL 3 requires storage within 168 hours of moisture exposure.
