Original Part
Transceiver, Non-Inverting 2 Element 8 Bit per Element 3-State Output 48-SSOP
Alternative Part
Transceiver, Non-Inverting 2 Element 8 Bit per Element 3-State Output 48-TSSOP
Transceiver, Non-Inverting 2 Element 8 Bit per Element 3-State Output 48-TSSOP
1. 74FCT162245ATPAG8 Substitution Conclusion
The 74FCT162245ATPAG8 is fully consistent with the original part 74FCT162245CTPVCG4 in terms of logic function and key electrical parameters, including non-inverting transceiver architecture, dual-element 8-bit configuration, tri-state outputs, 24mA drive current, and 4.5V–5.5V supply voltage. This confirms its viability as a direct functional replacement.
The difference lies in the package type: the original part uses a 48-BSSOP (7.50mm body width), while the 74FCT162245ATPAG8 uses a 48-TFSOP (6.10mm body width). The thinner package offers potential space savings but requires PCB layout re-evaluation, as pad dimensions and pin pitch may differ, which could introduce assembly compatibility issues or necessitate design adjustments.
Additionally, the manufacturer change from Texas Instruments to Renesas may affect supply chain availability and long-term reliability, though no substantive technical differences exist in the specifications.
2. 74FCT162245CTPAG Substitution Conclusion
The 74FCT162245CTPAG matches the original 74FCT162245CTPVCG4 exactly in core parameters such as logic type, number of elements, bit configuration, output characteristics, drive current, and voltage range, making it highly feasible as an electrical and functional substitute.
Again, the difference is in the package: the original part is housed in a 48-BSSOP (7.50mm wide), while the 74FCT162245CTPAG comes in a 48-TFSOP (6.10mm wide). The more compact package benefits high-density PCB applications but introduces mechanical compatibility challenges—such as potential redesign of the pad pattern or verification of pinout—to ensure proper mounting.
The manufacturer shift to Renesas may result in supply variations; however, given the identical performance specifications, the substitution is technically sound provided the package differences are properly addressed.
