MAX3188EUT-T

Overview

The MAX3188EUT-T is a single RS-232 transmitter integrated circuit manufactured by Analog Devices under the Maxim Integrated brand. Housed in a compact SOT-23-6 surface-mount package, this device provides full-duplex communication capabilities with one driver and zero receivers. It supports data rates up to 1 Mbps while maintaining low power consumption, drawing only 170 µA of operating supply current. The component operates within a voltage range of 5.4 V minimum to 5.4 V maximum, ensuring stable performance for serial interface applications requiring robust ESD protection rated at 15 kV.

Feature Summary

• Integrated ESD protection rated at 15 kV for enhanced signal integrity
• Compact SOT-23-6 packaging suitable for space-constrained designs
• Low quiescent current operation for battery-powered systems

Applications

• Portable handheld devices requiring serial communication
• Industrial control systems with limited board space
• Embedded systems utilizing RS-232 interfaces

Procurement Notes

Verify the exact ordering suffix against official manufacturer documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status directly with the supplier as regulatory markings may vary by production batch. Ensure the source distributor provides valid traceability records for quality assurance purposes prior to purchase.

Selection Notes

Select this component when a single-driver RS-232 solution is required in an ultra-small footprint. Verify that the system voltage aligns with the specified 5.4 V operational requirement. Consider the 1 Mbps data rate limit against application bandwidth needs. Evaluate thermal dissipation requirements based on the SOT-23-6 package constraints.

Part Context

This part belongs to the MAX3188 series of RS-232 transceivers designed for minimal size and power consumption. It complements other Maxim Integrated interface solutions by offering dedicated transmission functionality without integrated reception channels. The series targets applications where board real estate is critical but reliable serial data transmission remains essential.
