SP3222EBCA-L

Drivers, Receivers, Transceivers Overview

The SP3222EBCA-L is an RS-232 transceiver integrated circuit manufactured by MaxLinear. It features two drivers and two receivers, supporting full-duplex communication with a data rate of 235 kb/s. The device operates on a single power supply ranging from 3 V to 5.5 V and includes a shutdown mode that reduces operating current to 300 uA. It is housed in a 20-pin SSOP package and functions within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum output current of 35 mA and a propagation delay of 1 us for drivers and 0.3 us for receivers.

Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix configuration against official MaxLinear documentation to confirm pinout compatibility and thermal specifications. Confirm availability status through authorized distributors as lead times may vary. Ensure the component meets required environmental certifications for the target application before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring true RS-232 performance from a single low-voltage supply. Consider the 20-pin SSOP package constraints for PCB layout. Evaluate the shutdown current requirements against system power budgets. Verify that the 235 kb/s data rate meets the specific communication speed needs of the interface design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3222E series of intelligent RS-232 transceivers designed for portable applications. The series utilizes a high-efficiency charge pump to generate necessary voltage levels from a single 3V to 5.5V source. It is engineered to replace traditional dual-supply solutions, simplifying power management in battery-operated devices while maintaining standard RS-232 signal integrity.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct replacements within the SP3222E family with different suffixes indicating package or temperature variations. Verify pin-to-pin compatibility with existing designs if substituting with similar RS-232 transceivers from other manufacturers.
