Engineering Selection Recommendations
For applications requiring direct pin-compatible replacement of the obsolete XR3082XID-F, the MAX13082EESA+T and MAX13082EASA+ are the primary candidates. Both devices are manufactured by Analog Devices Inc./Maxim Integrated with active product status and ROHS3 compliance. The MAX13082EASA+ offers extended operating temperature range (-40°C to 125°C) compared to the MAX13082EESA+T (-40°C to 85°C), making it suitable for high-temperature environments.
For applications where higher data rate capability is required, the LTC1481 series (2.5 Mbps) provides superior performance. The LTC1481IS8#PBF and LTC1481IS8#TRPBF variants maintain the full -40°C to 85°C temperature range of the original XR3082XID-F. The LTC1485 series offers alternative receiver hysteresis characteristics (60 mV) with active product status and ROHS3 compliance.
All substitute parts maintain 8-SOIC surface mount packaging and half-duplex RS422/RS485 protocol compatibility. Supply voltage ranges differ slightly between device families; verify system voltage specifications before selection.
Frequently Asked Questions (FAQ)
Q: Can MAX13082EESA+T directly replace XR3082XID-F in existing designs?
A: Yes. Both devices share identical 8-SOIC packaging, RS422/RS485 half-duplex protocol, 1/1 driver/receiver configuration, and 4.5V to 5.5V supply voltage range. The MAX13082EESA+T is pin-compatible and functionally equivalent, with active product status and ROHS3 compliance.
Q: What is the difference between MAX13082EESA+T and MAX13082EASA+?
A: Both are direct equivalents with identical electrical specifications. The primary difference is operating temperature range: MAX13082EESA+T operates -40°C to 85°C, while MAX13082EASA+ extends to -40°C to 125°C. Packaging differs: MAX13082EESA+T uses Cut Tape & Digi-Reel, while MAX13082EASA+ uses Tube packaging.
Q: Why do LTC1481 and LTC1485 devices have different data rates and hysteresis values?
A: These are distinct product lines within the Analog Devices portfolio. LTC1481 supports 2.5 Mbps with 45 mV receiver hysteresis, while LTC1485 offers 60 mV hysteresis. Both maintain RS422/RS485 half-duplex operation and 8-SOIC packaging. Selection depends on application data rate requirements and noise immunity specifications.
Q: Are all substitute parts ROHS3 compliant?
A: All active substitute parts listed (MAX13082 and LTC148x series) are ROHS3 compliant. The original XR3082XID-F does not specify RoHS status due to its obsolete classification.
Q: What packaging options are available for LTC1481 and LTC1485 devices?
A: Both series are available in Tube and Tape & Reel (TR) packaging. The #PBF suffix indicates Tube packaging, while #TRPBF indicates Tape & Reel. Select based on procurement and assembly requirements.
Q: Can LTC1481 or LTC1485 be used in applications requiring 250 kbps operation?
A: Yes. Both LTC1481 (2.5 Mbps) and LTC1485 series support 250 kbps operation. The higher data rate capability of LTC1481 provides additional margin for future system upgrades without component replacement.
Q: What is the significance of the "I" and "C" temperature grade designations in LTC part numbers?
A: The "C" grade (LTC1481CS8, LTC1485CS8) operates 0°C to 70°C. The "I" grade (LTC1481IS8, LTC1485IS8) operates -40°C to 85°C, matching the full temperature range of the original XR3082XID-F. Select based on system operating environment requirements.
