Specifications and operating details

The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.

  • The SP385E offers +3.3V operation for EIA-562 and EIA-232 applications.
  • The SP385E is pin compatible to the LTC1385 EIA-562 transceiver with the exception that the drivers are disabled with the ON/OFF pin. ■ Operates from 3.3V or 5V Power Supply ■ Meets all EIA-232D and V.28 Specifica- tions at 5V. ■ Meets EIA.
  • Exposure to absolute maximum rating conditions for extended periods of time may affect reliability and cause permanent damage to the device.
  • Input Voltages Output Voltages Short-Circuit Duration VCC = +3.3V +10%; cap on (V+) and (V-) = 1.0µF, C1 = C2 = 0.1µF; TMIN to TMAX unless otherwise noted.

Engineering review checklist

  • Verify capacitance tolerance, rated voltage, temperature range and any DC-bias derating.
  • Check ESR, ripple-current capability, lifetime and polarity requirements under worst-case conditions.
  • Confirm package dimensions, land pattern and reflow or mounting limits for the selected ordering code.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
