MAX3188EEUT

Overview

The MAX3188EEUT+T is a single RS-232 transmitter manufactured by Analog Devices Inc./Maxim Integrated, housed in a compact SOT-23-6 surface-mount package. Designed for low-power applications, it operates at a fixed supply voltage of 5.4 V with a maximum operating current of 170 µA. The device supports data rates up to 250 kb/s and features integrated ESD protection rated at 15 kV. It functions as a full-duplex driver without an integrated receiver, making it suitable for space-constrained serial communication interfaces requiring robust noise immunity.

Feature Summary

• Integrated 15 kV electrostatic discharge (ESD) protection on all pins
• Ultra-low power consumption with 170 µA supply current
• Compact SOT-23-6 surface-mount packaging for space efficiency

Applications

• Portable battery-powered devices requiring RS-232 connectivity
• Industrial control systems with limited board space
• Embedded serial communication modules

Procurement Notes

Verify the complete part number including suffixes such as +T for reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the component meets specific environmental and regulatory requirements for the intended deployment region.

Selection Notes

Select this component when a single-driver RS-232 interface is required in a minimal footprint. It is appropriate for designs needing high ESD tolerance and low quiescent current. Verify that the system logic levels are compatible with the 5.4 V supply requirement before integration into the circuit design.

Part Context

This component belongs to the MAX3188E series of RS-232 transmitters from Maxim Integrated. The series focuses on providing reliable serial communication capabilities in small form factors. It serves as a specialized solution for applications where full transceivers are unnecessary or too large.

Replacement Considerations

Consult official substitution guides for equivalent single-driver RS-232 transmitters. Verify pin compatibility and electrical specifications against alternative part numbers before implementation.
