MAX3245EEUI+T

Overview

The MAX3245EEUI+T is a true RS-232 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single +3.0V to +5.5V supply and features three drivers and five receivers. The device guarantees data rates up to 1Mbps using MegaBaud operation. It incorporates AutoShutdown Plus technology, reducing supply current to 1μA when idle. ESD protection is rated at ±15kV for air discharge and ±8kV for contact discharge. The component is housed in a 28-pin TSSOP package and supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption during periods of inactivity or cable disconnection.
• Integrated dual charge pump generates internal voltage rails from a single low-voltage supply without external transformers.
• Enhanced I/O protection ensures robustness against electrostatic discharge events across various testing models.

Applications

• Notebook, subnotebook, and palmtop computers
• Cellular phones and battery-powered equipment
• Hand-held devices and peripherals such as printers

Procurement Notes

Verify the specific suffix EEUI+T corresponds to the required 28-TSSOP package and extended temperature range (-40°C to +85°C). Confirm RoHS compliance status via official manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this model over the MAX3244E variant when high-speed communication up to 1Mbps is required. Ensure the application utilizes a single +3.0V to +5.5V supply compatible with the integrated charge pump requirements.

Part Context

This component belongs to the MAX3245E series within the broader Maxim Integrated RS-232 interface portfolio. It shares architectural similarities with the MAX3224E through MAX3227E families but provides higher channel counts and faster data rate capabilities suitable for demanding serial communication interfaces.

Replacement Considerations

MAX3245EEUI is the non-tape reel equivalent. MAX3244EEUI+T offers identical pinout and package but is limited to 250kbps data rates.
