MAX3245EEUI

Overview

The MAX3245EEUI is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It integrates three drivers and five receivers within a single package, supporting data rates up to 1 Mbps. The device operates on a single power supply ranging from 3.0 V to 5.5 V. It features an autoshutdown function that reduces supply current to less than 1 µA when inputs are unpowered or grounded. The component provides 15 kV electrostatic discharge (ESD) protection on both transmit and receive lines. It is housed in a 28-pin Thin Shrink Small Outline Package (TSSOP).

Feature Summary

• Integrates three independent drivers and five independent receivers for expanded serial communication capabilities.
• Features an autoshutdown mechanism that significantly lowers power consumption during idle states or when host processors are off.
• Provides robust 15 kV ESD protection on all RS-232 signal pins to enhance reliability in harsh environments.

Applications

• Industrial control systems requiring multiple serial ports.
• Point-of-sale (POS) terminals with extended connectivity needs.
• Medical equipment utilizing RS-232 interfaces.
• GPS navigation devices with multi-channel communication requirements.

Procurement Notes

Verify the specific suffix EEUI confirms the TSSOP-28 package and industrial temperature range (-40°C to +85°C). Ensure compatibility with existing PCB footprints for 28-pin thin-shrink packages. Confirm RoHS compliance status if required by regional regulations. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

Selection Notes

Select this component when three drivers and five receivers are necessary within a single IC footprint. Consider the autoshutdown feature for battery-powered applications requiring low standby current. Verify that the 1 Mbps data rate meets system timing requirements. Ensure the operating voltage range aligns with the target system's power supply rails.

Part Context

This part belongs to the MAX3245E family of RS-232 transceivers designed for high-performance serial communications. It serves as a solution for applications needing more I/O channels than standard dual-driver parts provide. The EEUI suffix denotes the specific plastic package type and thermal characteristics defined by the manufacturer.

Replacement Considerations

Direct substitutes include other MAX3245 variants with different package options such as MAX3245ECAI+ for SSOP packaging. Check pin-to-pin compatibility before substitution. Verify that alternative parts maintain the same driver/receiver count and autoshutdown functionality.
