MAX3189EEUT+T

Overview

The MAX3189EEUT+T is a single RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for low-power serial communication applications. It operates within a supply voltage range of 4.5 V to 6 V, with a typical operating voltage of 5.4 V. The device supports data rates up to 1 Mb/s and features an ultra-low quiescent current consumption of 1 µA in shutdown mode. It is housed in a compact SOT-23-6 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with 1 µA shutdown current
• Single-supply operation compatible with standard RS-232 levels
• Compact SOT-23-6 packaging for space-constrained designs

Applications

• Portable battery-powered equipment requiring minimal standby current
• Industrial control systems with limited power budgets
• Embedded serial communication interfaces in compact devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure the ordering suffix matches the required tape-and-reel configuration. Validate that the supplier provides valid certification documents upon request.

Selection Notes

Select this component when a single-channel RS-232 interface is needed with strict power constraints. The SOT-23-6 package suits applications where board space is limited. Ensure the system design accommodates the 4.5 V to 6 V supply range and requires data rates up to 1 Mb/s. Verify thermal management capabilities for the specified operating temperature range.

Part Context

This part belongs to the MAX3189E series of single RS-232 transceivers. It shares architectural similarities with other Maxim integrated circuit solutions focused on low-power serial communications. The series emphasizes energy efficiency while maintaining standard RS-232 signal integrity for reliable data transmission in portable and industrial environments.

Replacement Considerations

Consult official datasheets for pin-compatible alternatives within the same product family. Verify electrical parameter equivalence before substitution. Check for updated manufacturing revisions that may affect performance characteristics.
