MAX3190EEUT-T

Overview

The MAX3190EEUT-T is an RS-232 interface integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a single driver transmitter with a data rate of 460 kbps. The device operates within a supply voltage range of 7.5 V to 12 V, with a typical operating voltage of 10 V. It features a shutdown capability and draws 250 uA of working power current. The output current is specified at 60 mA, with a power dissipation of 691 mW. It supports full-duplex communication and includes 15kV ESD protection on I/O pins. The component is housed in a SOT-23-6 package for surface mount installation.

Feature Summary

• Single-channel RS-232 transmitter driver
• Integrated 15kV electrostatic discharge protection
• Low-power shutdown mode functionality

Applications

• Portable battery-powered equipment requiring serial communication
• Industrial control systems with RS-232 interfaces
• Embedded devices needing compact signal conversion

Procurement Notes

Verify the exact suffix configuration against official manufacturer documentation before procurement. The 'T' suffix indicates tape and reel packaging, while 'E' denotes extended temperature range. Confirm availability status through authorized distributors, as this specific part number may be subject to limited supply or obsolescence. Ensure the ordering code matches the required package type and temperature grade to avoid integration errors.

Selection Notes

Select this component when a single-driver RS-232 solution is required in a minimal footprint. It is suitable for applications where only transmission is needed without integrated reception. Consider the 7.5 V to 12 V supply requirement, which differs from standard 5 V logic levels. Verify that the system design can accommodate the higher voltage swing and that the SOT-23-6 package aligns with the PCB layout constraints.

Part Context

This part belongs to the MAX3190 series of low-power RS-232 transmitters. It is designed to provide reliable serial communication in space-constrained environments. The device simplifies interface design by integrating charge pumps internally, eliminating the need for external capacitors in some configurations. It serves as a bridge between microcontroller UART signals and RS-232 line drivers.
