1. HI-4853PSHF Substitution Conclusion
The HI-4853PSHF is a viable functional replacement for the TL3695DR, as both are 1/1 half-duplex RS422/RS485 transceivers in compatible 8-SOIC packages. Key differences include: the data rate is specified as 20 Mbps (versus unspecified for the original), indicating the substitute may support higher communication speeds suitable for high-speed applications, though system compatibility should be verified to avoid signal integrity issues; the supply voltage range is wider (3.15V–5.5V vs. 4.75V–5.25V), allowing operation in both 3.3V and 5V systems and increasing design flexibility, but voltage stability must be ensured in strict 5V applications. The unspecified receiver hysteresis may introduce noise margin uncertainty; consulting the datasheet is recommended to assess EMC performance. Overall, substitution is feasible pending validation of data rate and hysteresis against the original design requirements.
2. LTC2862MPS8-1PBF Substitution Conclusion
The LTC2862MPS8-1PBF is a highly feasible replacement for the TL3695DR, as it is also a 1/1 half-duplex RS422/RS485 transceiver in a compatible 8-SOIC package. Notable differences include: a specified data rate of 20 Mbps (vs. unspecified for the original), enabling high-speed data transfer, though the original application should be evaluated to avoid overdrive or timing mismatches; a wider supply voltage range (3V–5.5V vs. 4.75V–5.25V), supporting operation from 3.3V to 5V systems and improving power supply adaptability, though voltage tolerance should be considered in pure 5V designs; higher receiver hysteresis (150mV vs. 120mV), providing improved noise immunity and enhanced signal stability in noisy environments. Overall, substitution is feasible and may offer superior performance, provided the high-speed and voltage parameters are compatible with the original system.
