The SP3232EE is a RS-232 transceiver IC manufactured by Sipex Corporation (now MaxLinear). It is designed to meet the needs of portable or handheld applications where space and power are critical. The SP3232EE uses a high-efficiency charge pump to meet the RS-232 voltage levels from a single 3.0V to 5.5V supply, consuming only 0.3mA of supply current.

Applications

• Notebook Computers
• Sub-Notebooks
• Handheld PCs
• PDAs
• Cellular Phones
• Battery-Powered Equipment

Features

• Meets all RS-232D and V.28 specifications
• Operates from a single +3.0V to +5.5V power supply
• Low power consumption: 0.3mA typical
• Internal charge pump requires only four small 0.1µF capacitors
• High data rate: Up to 120kbps
• Enhanced ESD specifications: ±15kV Human Body Model
• Available in SOIC and TSSOP packages
