MAX3209ECUU

Overview

The MAX3209ECUU is a fully compliant RS-232 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates six drivers and ten receivers within a single package, supporting full-duplex communication at data rates up to 460Kbps. The device operates on dual power supplies: 10.8V to 13.2V for the charge pump and 3V to 5.5V for logic interfaces. It features a 38-pin TSSOP surface-mount package with a 0.50mm pitch and 4.40mm width. The component includes 15kV ESD protection and maintains an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates six independent drivers and ten receivers for high-density serial communication
• Supports full-duplex operation with guaranteed data rates up to 460Kbps
• Provides robust 15kV electrostatic discharge protection on all lines
• Operates with separate voltage domains for charge pump and logic sections

Applications

• Motherboard serial port implementations
• Desktop computer interface circuits
• Industrial control systems requiring multiple RS-232 channels
• Communication equipment with high pin-count requirements

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm exact packaging and temperature grade variations. Confirm RoHS compliance status through current manufacturer datasheets as regulatory standards evolve. Ensure the supplier provides traceable origin records matching the Maxim Integrated branding history prior to acquisition by Analog Devices.

Selection Notes

Select this component when design requirements demand a high count of RS-232 transceivers in a compact footprint. The integrated charge pump eliminates external capacitor complexity compared to older generations. Verify that the system can accommodate the required dual voltage rails for optimal performance and signal integrity across the specified temperature range.

Part Context

This part belongs to the MAX3209E family of RS-232 transceivers designed for applications needing multiple serial ports. It represents a transition period product from Maxim Integrated before its integration into Analog Devices. The EC suffix denotes the industrial temperature grade and plastic TSSOP packaging variant suitable for automated surface-mount assembly processes.

Replacement Considerations

MAX3209EEUU+ offers identical electrical specifications in a tube package instead of tape-and-reel. Cross-reference with MAX3241 series if fewer drivers are sufficient, noting differences in driver/receiver counts and shutdown capabilities.
