MAX3188EEUT-T

Overview

The MAX3188EEUT-T is an RS-232 interface integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a single driver with no receiver, supporting full-duplex communication at data rates up to 250 kb/s. The device operates within a supply voltage range of 5.4 V (minimum and maximum) and consumes 170 uA of operating power supply current. It is housed in a SOT-23-6 package for surface mount installation. The component supports a shutdown feature and operates reliably across a temperature range from -40°C to +85°C.

Feature Summary

• Single-driver RS-232 transceiver architecture
• Integrated shutdown capability for power management
• SOT-23-6 compact surface-mount packaging

Applications

• RS-232 serial communication interfaces
• Industrial control systems requiring low-power transmission
• Embedded devices with limited board space

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as documentation may vary by production batch. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the supplier provides valid traceability documents matching the manufacturer's part number format.

Selection Notes

Select this component only if a single-driver configuration meets the system requirements, as it lacks an integrated receiver. Verify that the 250 kb/s data rate suffices for the application, noting that higher-speed alternatives exist within the family. Ensure the design accommodates the specific 5.4 V supply voltage constraint and SOT-23-6 thermal characteristics.

Part Context

This part belongs to the MAX3188E series of RS-232 drivers. It is distinct from receiver-only variants like the MAX3181 and dual driver/receiver combinations. The EEUT designation specifies the industrial temperature grade and SOT-23-6 package type within the Maxim Integrated portfolio.

Replacement Considerations

Direct substitutes include other single-driver RS-232 ICs in SOT-23-6 packages from Analog Devices. Verify pin compatibility and electrical specifications before swapping. Generic RS-232 drivers may require level-shifting adjustments.
