SP235BCP-L

Drivers, Receivers, Transceivers Overview

The SP235BCP-L is a dual RS-232 transceiver manufactured by Sipex, designed to provide full duplex communication over serial ports. It operates from a single +5V power supply and incorporates internal charge pumps to generate the necessary positive and negative voltages for RS-232 signaling without requiring external components. The device meets ITU-T V.28 and EIA/TIA-232-F interface standards. It features low power consumption with a shutdown mode drawing typically less than 1µA. The package is a standard 16-pin CP plastic small outline package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin as Sipex or its successor entities like Exar or Maxim Integrated, as corporate acquisitions may affect part numbering and datasheet availability. Confirm the suffix L indicates lead-free compliance if required by specific environmental regulations. Ensure the package type matches the design footprint requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual channel RS-232 solution is needed with minimal external bill of materials. It is suitable for applications requiring low standby current due to the integrated shutdown feature. Compare pin compatibility with other industry-standard RS-232 drivers if space constraints are critical.

Drivers, Receivers, Transceivers Part Context

This part belongs to the family of high-performance RS-232 line drivers and receivers that meet V.28 specifications. It shares functional similarities with devices like the SP202E and SP232E series, offering enhanced ESD performance and low power operation typical of Sipex's communication interface products.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible alternatives include the Exar XR235CPE and Maxim MAX235CPE. Verify voltage levels and ESD ratings when substituting with generic RS-232 transceivers to ensure system reliability.
