SP385EEA-L/TR

Drivers, Receivers, Transceivers Overview

The SP385EEA-L/TR is a low-power RS-232 line driver and receiver manufactured by MaxLinear, Inc. It operates on a single power supply ranging from 3 V to 5.5 V and supports data rates up to 120 kb/s. The device integrates two drivers and two receivers in a full-duplex configuration. It utilizes external 0.1 µF capacitors for charge pump functionality, eliminating the need for dual voltage supplies. The component features a shutdown mode that reduces power consumption significantly. It is housed in a 20-pin SSOP package and operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as MaxLinear or Exar, as ownership transitions may affect labeling. Confirm the package type is SSOP-20 and check for lead-free compliance markings. Ensure the suffix matches the specific tape-and-reel variant. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring dual RS-232 channels with minimal power usage. It is suitable for applications where space constraints favor integrated capacitor solutions over discrete components. Verify that the required data rate does not exceed 120 kb/s. Consider the thermal dissipation limits if operating at maximum load currents.
