MAX3190EUT+

Overview

The MAX3190EUT+ is an RS-232 interface integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It functions as a single driver transmitter supporting data rates up to 460 kb/s. 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 full-duplex communication capability and includes a shutdown function for power management. The component is housed in a SOT-23-6 surface-mount package and dissipates up to 691 mW of power. It draws 250 uA of working current and provides an output current of 60 mA. The operational temperature range spans from -40°C to +85°C.

Feature Summary

• Single-channel RS-232 transmitter design
• Integrated shutdown control for low-power operation
• Robust ESD protection capabilities

Applications

• Industrial automation systems
• Control network interfaces
• Embedded serial communication modules

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific packaging variants prior to ordering. Ensure supply chain documentation matches the exact MAX3190EUT+ designation to avoid substitution errors in critical industrial applications.

Selection Notes

Select this component when designing circuits requiring a compact, single-driver RS-232 solution with moderate speed requirements. The SOT-23-6 package suits space-constrained layouts. Verify that the required supply voltage aligns with the 7.5V to 12V operational window and that the 460kbps rate meets system timing constraints.

Part Context

This part belongs to the MAX3190 series of RS-232 drivers. It is distinct from transceivers like the MAX3190EUT+T which may include receiver components, and differs from higher-speed RS-485/RS-422 devices such as the MAX3094EEUE+T. It serves as a dedicated transmitter element within the broader Maxim interface portfolio.
