MAX3245EEWI

Overview

The MAX3245EEWI is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-pin TSSOP package. It operates on a single +3.0V to +5.5V supply and features three drivers and five receivers for full-duplex communication. The device guarantees a data rate of 1Mbps using MegaBaud technology. It incorporates AutoShutdown Plus, reducing supply current to 1μA when idle. ESD protection meets ±15kV (Air-Gap), ±8kV (Contact), and ±15kV (Human Body Model) standards per IEC 1000-4-2. The operating temperature range extends from -40°C to +85°C.

Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption by shutting down charge pumps during periods of inactivity.
• Integrated dual charge pump generates internal +5.5V and -5.5V supplies from a single low-voltage source.
• Enhanced electrostatic discharge protection ensures robustness against high-voltage static events on all I/O lines.

Applications

• Notebook, subnotebook, and palmtop computers
• Cellular phones and battery-powered equipment
• Hand-held devices and peripherals such as printers

Procurement Notes

Verify the specific suffix 'W' corresponds to the TSSOP package variant within official manufacturer documentation. Confirm that the component is lead-free and RoHS-compliant before procurement. Ensure the ordering information matches the required industrial temperature range specifications.

Selection Notes

Select this model for applications requiring high-speed 1Mbps transmission rates over standard RS-232 interfaces. The integrated AutoShutdown Plus feature makes it suitable for battery-operated systems where minimizing quiescent current is critical. Verify that the system voltage falls within the specified +3.0V to +5.5V operational range.

Part Context

This component belongs to the MAX3224E/MAX3225E/MAX3226E/MAX3227E/MAX3244E/MAX3245E family. These devices are designed as low-power, 3V-powered communications interfaces. The MAX3245E specifically provides higher channel counts compared to the two-driver variants in the same series.

Replacement Considerations

MAX3245ECAI+ and MAX3245EAI+ are verified substitutes within the same product family offering identical electrical characteristics and functionality.
