1. ADM3485EARZ-REEL7 Substitution Conclusion
This device can serve as a direct replacement and represents a performance upgrade. The key differences lie in data rate (10 Mbps vs. 2.5 Mbps) and receiver hysteresis (50 mV vs. 20 mV). The higher data rate enables faster communication speeds, making it suitable for systems with more demanding bus rate requirements. The increased receiver hysteresis provides stronger noise immunity, allowing more reliable signal detection in electrically noisy environments with significant common‑mode noise. This reduces false triggering and enhances communication robustness. Both devices are fully compatible in supply voltage and package pinout, enabling a drop‑in replacement that improves system performance.
2. ADM3072EYRZ-REEL7 Substitution Conclusion
This device is not a direct replacement and is only suitable for specific low‑speed applications. The most critical difference is the significantly lower data rate (250 kbps vs. 2.5 Mbps). It cannot support the high communication speed required by the original design; forced substitution would result in insufficient system communication bandwidth or complete failure. Although its receiver hysteresis is higher (100 mV vs. 20 mV), offering excellent noise immunity in extremely noisy environments, this does not compensate for the fundamental limitation in data rate. It should not be considered a direct replacement unless the target application explicitly operates at communication rates below 250 kbps.
