1. SN65HVD3088EDG4 Substitution Conclusion From the perspective of key technical parameters, the SN65HVD3088EDG4 is fully aligned with the original SP3088EEN-L/TR in terms of protocol, number of drivers/receivers, duplex mode, data rate, supply voltage, and package, providing a basis for direct substitution. The critical difference lies in its receiver hysteresis, which is only 30 mV—significantly lower than the 100 mV of the original part. Under the same noise conditions, the TI device exhibits weaker noise immunity and may be more prone to false triggering due to signal fluctuations, potentially compromising communication reliability. Substitution is feasible in applications with low electrical noise or good signal integrity. However, in noise-sensitive or industrially complex environments, the actual signal integrity risk should be evaluated; adjustments to peripheral circuitry or additional noise immunity design may be required.
