Substitute Part Grouping Explanation

Substitution of the CY74FCT16245CTPVC is determined by the following critical parameters:

Functional Compatibility Requirements:

Logic type must be Transceiver, Non-Inverting
Must have 2 elements with 8 bits per element
Output type must be 3-State
Operating temperature range must encompass -40°C ~ 85°C

Electrical Compatibility Requirements:

Supply voltage range must support 4.5V ~ 5.5V operation
Output current specifications (32mA high / 64mA low) define the drive capability class

Physical Compatibility Requirements:

Package must be 48-pin SSOP or compatible footprint (48-BSSOP or 48-TFSOP)
Surface mount configuration required

Substitute parts are grouped into two categories:

Category 1: Direct Electrical & Functional Equivalents (48-BSSOP Package) Parts maintaining identical supply voltage (4.5V ~ 5.5V), output current (32mA / 64mA), and 48-BSSOP package footprint.

Category 2: Functional Equivalents with Package Variation (48-TFSOP Package) Parts maintaining identical supply voltage and functional characteristics but using 48-TFSOP package (0.240", 6.10mm Width), which requires PCB layout adjustment but maintains electrical compatibility.

Category 3: Low-Voltage Alternative (1.65V ~ 3.6V Supply) Parts with reduced supply voltage range and lower output current specifications, suitable only for applications not requiring 5V operation.

Engineering Selection Recommendations

For Direct Replacement (Same Package, Same Electrical Performance):

The 74FCT16245CTPVG8 (IDT, Active status) provides the most direct substitution, maintaining the 48-BSSOP package footprint and identical output current specifications (32mA / 64mA). This part is currently in active production status, ensuring long-term availability and supply chain stability.

For Active Production Alternatives with Package Footprint Change:

Parts 74FCT16245ATPAG8, 74FCT16245CTPAG, and 74FCT16245CTPAG8 (all Renesas Electronics, Active status) maintain the 32mA / 64mA output current specification but use the 48-TFSOP package. These parts are ROHS3 compliant and actively manufactured. PCB layout modification is required to accommodate the different package footprint (0.240" vs 0.295" width).

For Reduced Output Current Applications:

Parts 74FCT162245ATPAG, 74FCT162245ATPVG, and 74FCT162245CTPAG provide functional equivalence with reduced output current (24mA / 24mA). These are suitable only for applications where the lower drive capability is acceptable. IDT and Renesas variants are available in active production status.

For Low-Voltage System Integration:

The SN74LVCR16245ADLR (Texas Instruments, Active status) operates at 1.65V ~ 3.6V supply voltage with reduced output current (12mA / 12mA). This part is suitable only for low-voltage applications and is not compatible with 5V systems.

Frequently Asked Questions (FAQ)

Q: Can I use 74FCT16245CTPVG8 as a direct replacement for CY74FCT16245CTPVC?

A: Yes. Both parts maintain identical electrical specifications (4.5V ~ 5.5V supply, 32mA / 64mA output current) and use the 48-BSSOP package. The 74FCT16245CTPVG8 is manufactured by IDT and holds active production status, providing supply continuity.

Q: What is the difference between 48-BSSOP and 48-TFSOP packages?

A: The 48-BSSOP package has a width of 0.295" (7.50mm), while the 48-TFSOP package has a width of 0.240" (6.10mm). Both are 48-pin surface mount packages with the same pin pitch and electrical compatibility. PCB layout and footprint design must be adjusted to accommodate the different package width.

Q: Can I substitute a part with 24mA / 24mA output current for the original 32mA / 64mA specification?

A: Substitution is possible only if the application circuit does not require the higher output current. The 24mA / 24mA parts (74FCT162245 series) have reduced drive capability and may not meet timing or loading requirements of circuits designed for 32mA / 64mA performance. Circuit analysis is required to confirm compatibility.

Q: Why is the CY74FCT16245CTPVC marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Texas Instruments. Active production alternatives from IDT and Renesas Electronics are available to support ongoing designs and procurement requirements.

Q: Is the SN74LVCR16245ADLR compatible with my 5V system?

A: No. The SN74LVCR16245ADLR operates at 1.65V ~ 3.6V supply voltage and is not compatible with 5V systems. This part is suitable only for low-voltage applications. Use 74FCT series parts for 5V operation.

Q: What does ROHS3 compliance mean for component selection?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. All recommended substitutes maintain ROHS3 compliance or equivalent environmental standards, ensuring regulatory compliance in manufacturing and end-use applications.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Inventory levels vary by part number and manufacturer. The 74FCT16245ATPAG (IDT) shows 6679 units in stock, while other variants show lower availability. Verify current inventory status with your supplier before finalizing component selection for production quantities.
