Engineering Selection Recommendations
For direct pin-compatible replacement in 48-BSSOP package format, 74FCT162245ATPVCT (Cypress Semiconductor) is the preferred substitute. This part maintains identical electrical specifications (24mA output current) and package dimensions while offering Active product status, ensuring long-term availability and supply chain stability. CY74FCT162245TPVCT provides an alternative from Cypress Semiconductor with equivalent specifications and Active status.
For applications where package footprint conversion is acceptable, 48-TFSOP variants including 74FCT162245ATPACT and 74FCT162H245ATPACT from Texas Instruments provide functionally equivalent substitutes with reduced package width (0.240" versus 0.295"). These parts maintain identical electrical performance and operating parameters.
Parts with higher output current specifications (32mA/64mA) such as 74FCT16245TPVCG4 and CY74FCT16245ATPACT are electrically compatible but provide enhanced drive capability. These variants are suitable for applications requiring higher output current without modification to circuit design.
All substitute parts listed maintain ROHS3 compliance and operate within the specified -40°C to 85°C temperature range. Moisture sensitivity levels vary between MSL 1 (Unlimited) for most substitutes and MSL 3 (168 Hours) for the original part, requiring appropriate handling procedures during assembly.
Frequently Asked Questions (FAQ)
Q: Can 74FCT162245ATPVCT be used as a direct replacement for 74FCT162245CTPVG?
A: Yes. Both parts share identical electrical specifications (24mA output current, 4.5V–5.5V supply, -40°C to 85°C operating range) and the same 48-BSSOP package footprint. The primary difference is manufacturer (Cypress versus Renesas) and product status (Active versus Obsolete).
Q: What is the difference between 48-BSSOP and 48-TFSOP packages?
A: Both are 48-pin surface mount packages with identical pin pitch and functionality. The 48-BSSOP measures 0.295" in width, while the 48-TFSOP measures 0.240" in width. PCB footprints differ, requiring layout modification for TFSOP variants.
Q: Are parts with 32mA/64mA output current compatible with designs specified for 24mA/24mA?
A: Yes. Higher output current capability is backward compatible. Circuits designed for 24mA operation function correctly with 32mA/64mA parts. No circuit modification is required.
Q: What does "Active" product status mean compared to "Obsolete"?
A: Active status indicates the manufacturer continues production and supports long-term availability. Obsolete status indicates production has ended. For new designs, Active parts (74FCT162245ATPVCT, CY74FCT162245TPVCT) are preferred for supply chain continuity.
Q: Do all substitute parts meet RoHS3 compliance?
A: Yes. All listed substitute parts are ROHS3 compliant. Moisture sensitivity levels vary; most substitutes specify MSL 1 (Unlimited), while the original part specifies MSL 3 (168 Hours), affecting storage and handling requirements.
Q: Can I use CY74FCT16245ATPACT as a substitute?
A: CY74FCT16245ATPACT is electrically compatible but features higher output current (32mA/64mA) and a different package format (48-TFSOP). It functions as a substitute only if the PCB layout accommodates the TFSOP footprint and higher drive capability is acceptable.
