MAX3190EUT-T

Overview

The MAX3190EUT-T is an RS-232 interface integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It functions as a single transmitter driver housed in a compact SOT-23-6 surface-mount package. The device supports data rates up to 460 kb/s and operates with a supply voltage range of 7.5 V to 12 V, typically utilizing a 10 V nominal supply. Key electrical characteristics include a maximum output current of 60 mA and a power dissipation rating of 691 mW. It features a shutdown mode for power conservation and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Single-channel RS-232 transmitter driver functionality
• Integrated shutdown control for low-power operation
• Compact SOT-23-6 surface-mount packaging

Applications

• Portable battery-powered equipment requiring serial communication
• Industrial control systems with limited board space
• Embedded devices needing RS-232 signal transmission

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to restricted availability status. Confirm that the specific suffix matches the required tape-and-reel configuration if applicable. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

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 capability is needed without an integrated receiver. Consider the 7.5 V to 12 V operating range and ensure the system power architecture supports these voltage levels efficiently.

Part Context

This part belongs to the MAX3190 series of RS-232 transceivers designed for space-constrained applications. It represents a simplified version of full transceivers, focusing solely on the transmit path. The series is known for integrating charge pump circuitry internally to generate the necessary voltages for RS-232 signaling from a single low-voltage supply.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and functional compatibility with any potential alternatives before implementation.
