1. LTC1482IS8PBF Substitution Conclusion
Direct substitution is not recommended. The LTC1482IS8PBF differs in that its data rate is limited to 4 Mbps (significantly lower than the original part’s 30 Mbps), and its receiver hysteresis is only 30 mV (compared to 50 mV for the original device). This part is suitable only for low‑speed communication scenarios and exhibits weaker noise immunity in electrically noisy environments. It may not meet the original design’s reliability requirements for high‑bandwidth or harsh electrical conditions.
2. ISL4485EIBZ‑T Substitution Conclusion
Substitution is acceptable in most applications, provided rate compatibility is verified. The ISL4485EIBZ‑T supports a data rate of 20 Mbps (lower than the original 30 Mbps), while its receiver hysteresis is 70 mV (higher than the original 50 mV). This results in slightly reduced communication bandwidth but improved noise rejection. The device is well‑suited for applications where noise immunity is prioritized over maximum speed. However, if the original system operates close to 30 Mbps, substitution could lead to communication instability.
