MAX3245EWI

Overview

The MAX3245EWI is a true RS-232 transceiver from the MAX3224–MAX3245 family, manufactured by Analog Devices Inc./Maxim Integrated. It features three drivers and five receivers with full-duplex operation. The device supports data rates up to 1Mbps using MegaBaud technology and operates on a single +3.0V to +5.5V supply. It incorporates AutoShutdown Plus functionality, reducing supply current to 1µA when inputs are inactive for over 30 seconds. The component utilizes a dual charge pump requiring four external capacitors and is housed in a 28-pin Wide SOIC package.

Feature Summary

AutoShutdown Plus feature automatically reduces power consumption when idle
MegaBaud capability ensures reliable high-speed communication at 1Mbps
Proprietary low-dropout transmitter output stage maintains signal integrity
Dedicated R2OUTB pin allows continuous monitoring during shutdown states

Applications

Notebook, subnotebook, and palmtop computers
Cellular phones and handheld equipment
Battery-powered peripherals and printers

Procurement Notes

Verify the specific suffix 'EWI' against official documentation to confirm the exact package type and temperature range. Confirm RoHS compliance status for the specific ordering code. Ensure the source document explicitly lists this part number variant before procurement.

Selection Notes

Select the MAX3245EWI for applications requiring three drivers and five receivers with high-speed 1Mbps performance. This model is suitable for systems needing automatic power management via AutoShutdown Plus. Verify that the 28-pin Wide SOIC package fits the design constraints compared to TSSOP or SSOP alternatives.

Part Context

This component belongs to the MAX3224–MAX3227/MAX3244/MAX3245 series of low-power RS-232 transceivers. It shares core technologies like AutoShutdown Plus and dual charge pumps with siblings such as the MAX3244 and MAX3225. The primary distinction lies in the driver/receiver count and guaranteed data rate specifications within the same functional family.

Replacement Considerations

The MAX3244E is a compatible alternative offering identical functionality but limited to 250kbps data rates. The MAX3225 provides similar speed but differs in the number of drivers and receivers.
