Engineering Selection Recommendations
Primary Substitutes (Electrical and Mechanical Match): Parts matching all electrical parameters and output current specifications are 74FCT162245ATPACT, 74FCT162245CTPACT, 74FCT162H245ATPACT, 74FCT162H245CTPACT, CY74FCT162245ATPVC, and CY74FCT162245CTPVC. These maintain 24mA output current capability and are ROHS3 compliant with MSL 1 rating.
Active Status Alternative: 74FCT162H245CTPVC (Cypress Semiconductor) and CY74FCT162245ATPVC (Cypress Semiconductor) are classified as active products, providing extended availability compared to obsolete alternatives.
Package Consideration: 74FCT16245TPVCG4 provides equivalent functionality in the 48-BSSOP package but features higher output current (32mA high, 64mA low). This part is suitable only if the application requires increased drive capability.
Compliance Status: All substitute parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage requirements.
Frequently Asked Questions (FAQ)
Q: Can I substitute 74FCT162245ATPACT for 74FCT162245ATPVG8? A: Yes. Both parts share identical electrical specifications: 2-element, 8-bit transceiver, non-inverting logic, 3-state output, 24mA output current, and 4.5V to 5.5V supply range. The primary difference is package format: 48-TFSOP (0.240" width) versus 48-BSSOP (0.295" width). PCB layout must accommodate the different package dimensions.
Q: What is the difference between 74FCT162245 and 74FCT162H245 base part numbers? A: Both base numbers represent the same functional transceiver with identical electrical parameters. The "H" designation indicates a variant within the 74FCT series. Substitution between these base numbers is valid when all other electrical and package specifications match.
Q: Why does 74FCT16245TPVCG4 have different output current ratings? A: This part variant specifies 32mA high and 64mA low output current, compared to the standard 24mA for both high and low. This higher drive capability makes it suitable for applications requiring increased output current, but it is not a direct electrical equivalent for designs expecting 24mA symmetrical output.
Q: Are Cypress Semiconductor parts direct replacements? A: Yes. CY74FCT162245ATPVC and CY74FCT162245CTPVC are functionally equivalent to Renesas and Texas Instruments equivalents, with identical electrical specifications and package compatibility. Cypress parts classified as active provide better long-term availability.
Q: What packaging options are available for substitutes? A: Substitutes are available in two surface mount packages: 48-BSSOP (0.295" width) and 48-TFSOP (0.240" width). Both packages are compatible with standard SMT assembly processes. Verify PCB footprint compatibility before selection.
Q: Are all substitute parts ROHS3 compliant? A: All listed substitute parts are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, matching the compliance profile of the original 74FCT162245ATPVG8.
