1. 74FCT162H245ATPVC Substitution Conclusion
From the perspectives of core logic functionality, electrical parameters, and pin configuration, the 74FCT162H245ATPVC can serve as a substitute for the original part. Both are non-inverting, 8-bit dual-channel, tri-state transceivers with identical supply voltage range (4.5V–5.5V) and drive capability (24mA). The primary difference lies in the package: the original part (Renesas) is in a 48-TFSOP package (width 6.10mm), whereas the substitute (TI) is in a 48-SSOP/BSSOP package (width 7.50mm). PCB layout modifications are therefore mandatory, as the footprint dimensions and pin pitch likely differ, preventing a direct pad-for-pad replacement. A PCB redesign or an adapter solution is required.
2. 74FCT162H245CTPVC Substitution Conclusion
The 74FCT162H245CTPVC is also a viable functional substitute for the original part. Within TI's product line, this device is typically a different commercial variant of the same silicon as the 74FCT162H245ATPVC (often differing in reel packaging, lead-free designators, or lot code markings). Consequently, the technical comparison with the original part yields the same conclusion: key parameters such as logic function, voltage, and current are identical, but the packages are incompatible (48-SSOP/BSSOP vs. 48-TFSOP). Feasibility of the substitution hinges entirely on resolving the physical footprint and pad layout mismatch; from a circuit functionality standpoint, it is a direct replacement.
