Engineering Selection Recommendations
For direct pin-compatible replacement in 48-BSSOP package format, 74FCT162H245CTPVC (Cypress Semiconductor) is the preferred substitute. This part maintains identical electrical specifications (24mA output current, 4.5V–5.5V supply, -40°C to 85°C operating range) and is currently in active production status with higher inventory availability (8,365 units). Both CY74FCT162245ATPVC and CY74FCT162245CTPVC from Cypress Semiconductor are also viable 48-BSSOP alternatives with active product status.
For applications where package transition to 48-TFSOP (0.240", 6.10mm Width) is acceptable, 74FCT162245ATPACT and 74FCT162245CTPACT from Texas Instruments provide equivalent electrical performance with ROHS3 compliance and MSL rating of 1 (Unlimited).
The part 74FCT16245TPVCG4 differs in output current specification (32mA high, 64mA low) and should only be selected if the application circuit specifically requires higher output drive capability.
All recommended substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.
Frequently Asked Questions (FAQ)
Q: Can 74FCT162H245CTPVC be used as a direct replacement for 74FCT162245CTPVG8?
A: Yes. Both parts share identical electrical specifications: 2-element, 8-bit transceiver configuration, 24mA output current, 4.5V–5.5V supply voltage, and -40°C to 85°C operating temperature. Both use 48-BSSOP packaging. The primary difference is product status (74FCT162H245CTPVC is active; 74FCT162245CTPVG8 is obsolete) and manufacturer (Cypress vs. Renesas).
Q: What is the difference between 48-BSSOP and 48-TFSOP packages?
A: Both are surface-mount packages with 48 pins. The 48-BSSOP measures 0.295" (7.50mm) in width, while 48-TFSOP measures 0.240" (6.10mm) in width. The TFSOP variant is narrower and may require PCB layout adjustment. Electrical performance is identical between parts using these different packages.
Q: Why does 74FCT16245TPVCG4 have different output current ratings?
A: The 74FCT16245TPVCG4 specifies 32mA high and 64mA low output current, compared to 24mA for both high and low on the original part. This represents a different device variant within the 74FCT family. Selection should be based on circuit drive requirements; higher current capability may not be necessary for all applications.
Q: Are all substitute parts ROHS3 compliant?
A: Most substitutes listed are ROHS3 compliant. Cypress Semiconductor parts (74FCT162H245CTPVC, CY74FCT162245ATPVC, CY74FCT162245CTPVC) do not specify RoHS status in the provided data. Verify RoHS compliance requirements with your procurement specification before final selection.
Q: What does MSL rating mean, and why does it vary?
A: Moisture Sensitivity Level (MSL) indicates how long a component can be exposed to ambient moisture before soldering. The original part has MSL 3 (168 hours maximum), while most substitutes have MSL 1 (unlimited). Lower MSL ratings provide greater handling flexibility and reduce risk of moisture-induced defects during assembly.
Q: Can I use CY74FCT162245CTPVC if my design requires active product status?
A: No. CY74FCT162245CTPVC is listed as obsolete. For active product status, select 74FCT162H245CTPVC or CY74FCT162245ATPVC from Cypress Semiconductor, both of which are in active production.
