1. ISL83072EIBZA Substitution Conclusion
The ISL83072EIBZA is largely compatible with the original ADM3072EYRZ-REEL7 in terms of supply voltage (3V–3.6V), package (8-SOIC), protocol (RS422/RS485), and half-duplex operation. However, its receiver hysteresis is significantly reduced from 100 mV to 15 mV, which represents a notable difference. The lower hysteresis decreases noise margin and may increase the risk of false triggering in electrically noisy environments, potentially affecting communication reliability. This device is therefore only suitable for low-noise applications or scenarios where hysteresis is not critical. When substituting, system noise levels should be evaluated to ensure stability.
2. LTC2850HS8TRPBF Substitution Conclusion
The LTC2850HS8TRPBF is fully compatible with the original ADM3072EYRZ-REEL7 in voltage, package, and protocol, but presents two key differences: the data rate is increased from 250 kbps to 20 Mbps, and receiver hysteresis is reduced from 100 mV to 25 mV. The higher data rate supports high-speed communication and is suitable for systems requiring upgraded bandwidth, though it may lead to increased power consumption and EMI. While the hysteresis reduction is less severe than that of the ISL83072EIBZA, it still slightly reduces noise margin and should be considered carefully in noise-sensitive applications. Overall, this device is a viable substitute, particularly for designs that require higher transmission speed in well-controlled noise environments.
