MAX3389ECUG

Overview

The MAX3389ECUG+ is a low-power RS-232 transceiver designed for portable applications, manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single 2.5V to 5.5V supply and features three drivers and two receivers with full-duplex communication at data rates up to 120kbps. The device incorporates AutoShutdown Plus technology, reducing quiescent current to 1µA in shutdown mode. It provides ±15kV ESD protection on all pins and includes an integrated charge pump. The component is housed in a 24-pin TSSOP package.

Feature Summary

• AutoShutdown Plus technology enables ultra-low power consumption during idle periods
• Integrated charge pump eliminates the need for external capacitors
• Robust ±15kV ESD protection ensures reliability in harsh environments
• Single-supply operation supports battery-powered mobile devices

Applications

• Personal Digital Assistants (PDAs)
• Cell phone data cables
• Subnotebook and palmtop computers
• Battery-powered handheld equipment

Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature range and 'UG+' denotes the lead-free TSSOP-24 package configuration. Confirm RoHS compliance status through official manufacturer documentation before integration into production designs.

Selection Notes

Select this component when designing systems requiring minimal standby current and high ESD immunity. Ensure the application voltage aligns with the 2.5V to 5.5V operating range. Verify that the 24-pin TSSOP footprint matches the target PCB layout constraints.
