Alternative Part
1. ISL83072EIBZA Substitution Conclusion
Direct substitution is not recommended. The data rate of the ISL83072EIBZA (250 kbps) is significantly lower than the original part's 1 Mbps, which may fail to meet timing requirements in high-speed communication scenarios. Additionally, its receiver hysteresis (15 mV) is only 43% of the original's (35 mV), resulting in weaker noise margin. This could increase the risk of bit errors in noisy industrial environments. Although the supply voltage and package are compatible, the degradation of these two key performance parameters limits its reliability in the original high-speed or high-noise design.
2. ADM3078EARZ Substitution Conclusion
This device is electrically compatible and offers improved performance. The ADM3078EARZ supports a data rate of 16 Mbps, far exceeding the original part's 1 Mbps, enabling higher bandwidth communication. Its receiver hysteresis (100 mV) is nearly three times that of the original, providing significantly stronger noise immunity in environments with common-mode noise or signal ringing. Since both the supply voltage and package are identical, it can be directly substituted and is suitable for more demanding communication scenarios. However, attention must be paid to layout integrity at high data rates to avoid signal integrity issues.
