Substitute Part Grouping Explanation

Substitution for the PI74FCT16245ATVE is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

Logic Type: Transceiver, Non-Inverting (must match exactly)
Number of Elements: 2
Number of Bits per Element: 8
Output Type: 3-State
Voltage - Supply: 4.5V ~ 5.5V
Operating Temperature: -40°C ~ 85°C (TA)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant

Package Compatibility Considerations: The PI74FCT16245ATVE uses a 48-BSSOP package (0.295", 7.50mm Width). Substitutes may use either 48-BSSOP or 48-TFSOP (0.240", 6.10mm Width) packages, as both are surface mount 48-pin configurations suitable for the same functional application.

Output Current Variations: The original part specifies 32mA (High) and 64mA (Low) output current. Substitute parts with 24mA (High) and 24mA (Low) output current are functionally compatible, as these represent reduced but adequate drive capability for the same logic family and voltage range.

Engineering Selection Recommendations

Primary Substitutes (Matching Output Current Specification):

Parts 74FCT16245ATPAG, 74FCT16245ATPAG8, and 74FCT16245CTPAG maintain the original 32mA/64mA output current specification and are classified as Active products. These provide direct functional equivalence with current availability. The 48-TFSOP package variant requires PCB layout adjustment but maintains electrical compatibility.

Secondary Substitutes (Reduced Output Current):

Parts 74FCT162245ATPACT, 74FCT162245ATPAG, 74FCT162245ATPVG, 74FCT162245CTPACT, 74FCT162245CTPAG, and 74FCT162245CTPAG8 operate with 24mA/24mA output current. These are functionally compatible within the 74FCT logic family and voltage specification. The 74FCT162245ATPVCT (Cypress Semiconductor Corp) is the only Active-status part in this group and offers 48-BSSOP package compatibility with the original part.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and operate within the specified -40°C to 85°C temperature range. Parts with Active product status (74FCT162245ATPVCT, 74FCT162245CTPAG, 74FCT162245CTPAG8, 74FCT16245ATPAG, 74FCT16245ATPAG8, 74FCT16245CTPAG) offer superior long-term availability compared to Obsolete-status alternatives.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 74FCT162245 part for the PI74FCT16245ATVE?

A: Yes, with output current consideration. The 74FCT162245 series maintains identical logic type, element count, bit configuration, output type, voltage supply, and temperature range. However, output current is reduced from 32mA/64mA to 24mA/24mA. This is acceptable for applications where the lower drive capability is sufficient.

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

A: Both are 48-pin surface mount packages. The 48-BSSOP is 0.295" (7.50mm) wide, while the 48-TFSOP is 0.240" (6.10mm) wide. The TFSOP variant is narrower and requires different PCB footprint design. Electrical functionality is identical.

Q: Why are some parts listed as Obsolete and others as Active?

A: Product status reflects manufacturer availability. Active parts are currently in production and offer better long-term supply assurance. Obsolete parts may have limited inventory but are still functionally equivalent. For new designs, Active-status parts are preferred.

Q: Does the PI74FCT16245ATVE require an exact match for substitution?

A: No. Substitutes must match the core electrical parameters: non-inverting transceiver logic, 2 elements, 8 bits per element, 3-state output, 4.5V–5.5V supply, and -40°C to 85°C operating range. Package type and output current can vary within the specified tolerance.

Q: Which substitute offers the best availability?

A: The 74FCT162245ATPVCT (Cypress Semiconductor Corp) is the only Active-status part with 48-BSSOP package compatibility, matching the original package footprint while maintaining full electrical equivalence.
