Description

The SP3223EEP is an RS-232 transceiver solution that falls under the category of IC chips. It is primarily designed and recommended for use in portable or handheld devices like notebook and palmtop computers. This component uses an internal high-efficiency charge-pump power supply, which makes it ideal for 3.3V operation, and 0.1µF capacitors are required. The device's Sipexs driver architecture enables it to deliver consistent and compliant RS-232 performance from a single power supply, ranging from +3.3V to +5.0V. It is available in two variants, the SP3223EEP, which is a 2-driver/2-receiver device, while the SP3243EEP is a 3-driver/5-receiver device ideal for laptop/notebook computer and PDA applications.

Specifications and features

• Meets true EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply
• Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source
• AUTO ON-LINE® circuitry automatically wakes up from a 1µA shutdown
• Minimum 120Kbps data rate under load
• Regulated Charge Pump Yields Stable RS-232 Outputs Regardless of VCC Variations
• Enhanced ESD Specifications: +15KV Human Body Model, +15KV IEC1000-4-2 Air Discharge, +8KV IEC1000-4-2 Contact Discharge

Application Scenarios

The SP3223EEP is suitable for applications that require RS-232 transceiver solutions in portable or handheld devices, particularly in notebook and palmtop computers. It is also ideal for 3-driver/5-receiver devices that are used in laptop, notebook computer, and PDA applications.
