MAX3190EEUT

Overview

The MAX3190EEUT+T is an RS-232 interface integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a single transmitter with 15kV ESD protection and supports data rates up to 460kbps. The device operates within a supply voltage range of 3V to 5.5V and is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Integrated RS-232 transmitter with built-in charge pump
• High electrostatic discharge protection rating
• Low power consumption suitable for portable applications

Applications

• Portable communication devices
• Handheld terminals
• Battery-powered equipment requiring serial connectivity

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status and check current availability as supply may be restricted. Ensure the ordering suffix matches the required tape-and-reel packaging configuration for automated assembly processes.

Selection Notes

Select this component when a single-channel RS-232 transmitter is required in minimal space. It is appropriate for designs needing robust ESD immunity without external components. Consider the SOT-23-6 footprint constraints and thermal requirements during PCB layout planning.

Part Context

This part belongs to the MAX3189E/MAX3190E series of low-power RS-232 transmitters. It provides a simplified solution for point-to-point serial communication links where only transmission capability is needed, distinguishing it from full transceivers that include receiver channels.

Replacement Considerations

MAX3189EEUT+T serves as a functional substitute within the same series offering similar RS-232 transmitter capabilities and package compatibility.
