Engineering Selection Recommendations

Direct Parametric Equivalent (Identical Electrical Specifications): The 74ACT16245DL from Texas Instruments provides identical electrical performance with matching 24mA output current and 4.5V to 5.5V supply voltage. This part maintains Last Time Buy status, offering a transition path for designs currently using the obsolete CY74FCT162245TPVC.

Manufacturer-Recommended Substitute (Enhanced Availability): The 74FCT162245CTPAG and 74FCT162245CTPAG8 from IDT maintain identical electrical specifications (24mA output current, 4.5V to 5.5V supply) and are currently in active production status. These parts are available in 48-TFSOP packaging, which is mechanically compatible with the original 48-BSSOP footprint for surface mount applications.

Low-Voltage Alternative: The SN74LVCR162245DLR from Texas Instruments is an active production alternative designed for 2.7V to 3.6V supply voltage operation. This part is suitable for designs requiring lower voltage operation while maintaining the same functional architecture and 48-BSSOP package compatibility.

Higher Output Current Options: The 74FCT16245 series variants (74FCT16245ATPAG, 74FCT16245ATPAG8, 74FCT16245ATPVG, 74FCT16245CTPAG, 74FCT16245CTPAG8) provide increased output current capability (32mA high, 64mA low) while maintaining 4.5V to 5.5V supply voltage and operating temperature specifications. These parts are suitable for applications requiring higher drive capability.

All recommended substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the SN74LVCR162245DLR be used as a direct replacement for the CY74FCT162245TPVC? A: The SN74LVCR162245DLR is functionally equivalent but operates at a different supply voltage range (2.7V to 3.6V versus 4.5V to 5.5V). It is suitable only for designs that can operate at the lower voltage specification. Output current is also reduced to 12mA. Verify your circuit's voltage requirements before substitution.

Q: What is the difference between 48-BSSOP and 48-TFSOP packages? A: Both are 48-pin surface mount packages with different body widths. The 48-BSSOP is 0.295" (7.50mm) wide, while the 48-TFSOP is 0.240" (6.10mm) wide. The 48-TFSOP is mechanically compatible with 48-BSSOP footprints in most applications, though PCB layout verification is recommended.

Q: Are the 74FCT16245 variants (without "162" in the part number) compatible with the CY74FCT162245TPVC? A: The 74FCT16245 variants maintain the same functional architecture (2 elements, 8 bits per element, non-inverting transceiver, 3-state output) and supply voltage range (4.5V to 5.5V). However, they provide higher output current (32mA high, 64mA low). These parts are compatible for applications where increased drive capability is acceptable or beneficial.

Q: Which substitute part offers the best long-term availability? A: The 74FCT162245CTPAG and 74FCT162245CTPAG8 from IDT are currently in active production status with the highest inventory levels (2527 and 2175 units respectively). These parts maintain identical electrical specifications to the original CY74FCT162245TPVC.

Q: Do all substitute parts maintain the same compliance certifications? A: All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings. Verify specific REACH and ECCN requirements for your application, as these may vary by supplier and region.

Q: Can I use the higher output current 74FCT16245 variants in place of the CY74FCT162245TPVC? A: Yes, the 74FCT16245 variants are backward compatible. Higher output current capability does not create compatibility issues in circuits designed for the original 24mA specification. These parts are suitable for applications requiring improved drive capability or as general-purpose replacements.
