MAX3245CAI+G1Z

Overview

The MAX3245CAI+G1Z is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features three drivers and five receivers, supporting full-duplex communication at data rates up to 1Mbps. The device operates on a single +3.0V to +5.5V supply with an AutoShutdown Plus feature that reduces supply current to 1μA when idle. It includes ±15kV ESD protection on all inputs and outputs. The component is housed in a 28-pin SSOP package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• AutoShutdown Plus technology automatically enters low-power shutdown mode when the interface is inactive for over 30 seconds, reducing supply current to 1μA without BIOS modifications.
• Integrated dual charge pump generates internal +5.5V and -5.5V supplies from a single +3.0V to +5.5V external source using only four small capacitors.
• Enhanced electrostatic discharge protection rated at ±15kV via IEC 1000-4-2 Air-Gap Discharge, ±8kV Contact Discharge, and ±15kV Human Body Model.

Applications

• Notebook, Subnotebook, and Palmtop Computers
• Cellular Phones and Battery-Powered Equipment
• Hand-Held Equipment and Peripherals
• Printers and Automotive Systems

Procurement Notes

Verify the specific suffix G1Z against official manufacturer documentation to confirm lead-free/RoHS compliance status and exact package variant. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the ordering information matches the required temperature grade and pin configuration for your design.

Selection Notes

Select this component for applications requiring high-speed 1Mbps RS-232 communication with strict power constraints. The MAX3245E variant is suitable where MegaBaud operation is necessary compared to the 250kbps MAX3244E. Consider the 28-pin SSOP footprint for space-constrained designs needing multiple receiver channels.

Part Context

This part belongs to the MAX3224E/MAX3225E/MAX3226E/MAX3227E/MAX3244E/MAX3245E family of 3V-powered EIA/TIA-232 communications interfaces. These devices share common features like AutoShutdown Plus and high ESD protection but differ in driver/receiver counts and guaranteed data rates.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with MAX3244E if 250kbps speed is sufficient, or check other variants within the MAX32xxE series for different pin counts or packages.
