1. Substitution Conclusion for 74FCT16245CTPAG
The 74FCT16245CTPAG can serve as a direct replacement for the original part. The two devices are fully functionally compatible, with key parameters—including logic type, drive capability, and voltage range—remaining identical. However, there is a difference in package footprint: the substitute device is housed in a narrower 48-TSSOP (6.10mm wide), whereas the original part uses a 48-BSSOP (7.50mm wide). From a PCB design standpoint, it is essential to verify the pad compatibility. If the original layout was designed for the BSSOP package, trace adjustments will be required; otherwise, physical installation may not be possible. Electrically, however, the substitution can be implemented seamlessly.
2. Substitution Conclusion for 74FCT163245CPVG
The 74FCT163245CPVG is not a direct substitute for the original part due to two critical parameter differences. First, its voltage range is limited to 2.7V–3.6V (compared to 4.5V–5.5V for the original), making it a 3.3V logic device that is incompatible with 5V system voltage. Second, its drive capability is significantly reduced, with output current ratings of 8mA/24mA versus the original’s 32mA/64mA, which may result in insufficient load driving capacity. If used in a 5V system, these discrepancies could lead to signal level mismatch, driver failure, or even device damage. Therefore, this substitute is suitable only for 3.3V low-voltage design applications.
