MAX3189EEUT-T

Overview

The MAX3189EEUT-T is an RS-232 interface integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. 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 of 1 uA. 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 uA quiescent current for battery-operated applications
• High-speed serial communication capability supporting up to 1 Mb/s data rates
• Compact SOT-23-6 surface-mount packaging designed for space-constrained designs

Applications

• Portable handheld devices requiring low-power serial communication
• Industrial control systems with limited power budgets
• Battery-powered instrumentation and monitoring equipment

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm RoHS compliance status and specific lot traceability requirements prior to acquisition. Ensure the ordering suffix matches the exact reel or cut tape configuration needed for assembly processes. Cross-reference the full part number against current availability lists as supply constraints may affect procurement timelines.

Selection Notes

Select this component when designing systems that require RS-232 transmission in a minimal footprint. The SOT-23-6 package offers significant size reduction compared to traditional DIP or SOIC options. Evaluate the 1 uA standby current against total system power budgets for portable applications. Ensure the 4.5 V to 6 V supply range aligns with the target power rail architecture.

Part Context

This component belongs to the MAX3189E series of single RS-232 transmitters. It complements other Maxim Integrated interface solutions by providing a highly integrated, low-power alternative for serial data transmission. The series is engineered for applications where board space and energy efficiency are critical design parameters.

Replacement Considerations

Consult official datasheets for pin-compatible alternatives within the MAX3189 family. Verify electrical specifications and package dimensions before substituting any related part numbers.
