MAX3225EUP+T

Overview

The MAX3225EUP+T is a dual driver, dual receiver RS-232 transceiver in a 20-pin TSSOP package. It operates from a single +3.0V to +5.5V supply and achieves a typical supply current of 1µA via AutoShutdown Plus. The device guarantees a maximum data rate of 1Mbps with a propagation delay of 0.15µs. It includes an internal dual charge pump requiring four 0.1µF capacitors for operation at 3.3V.

Feature Summary

• AutoShutdown Plus technology automatically reduces power consumption when the interface is idle or disconnected.
• MegaBaud capability ensures reliable high-speed communication up to 1Mbps.
• Integrated dual charge pump generates required voltage levels without external inductors.

Applications

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

Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) and '+' denotes lead-free/RoHS compliance. Confirm the 'T' suffix corresponds to tape-and-reel packaging if reel quantity is required for automated assembly processes.

Selection Notes

Select this component over the MAX3224 or MAX3226 variants specifically when a guaranteed 1Mbps data rate is necessary. Ensure the design accommodates the 20-pin TSSOP footprint and provides adequate thermal dissipation for the exposed pad configuration.

Part Context

This part belongs to the MAX3224–MAX3227 family of EIA/TIA-232 interfaces. It shares core architecture with the MAX3224 and MAX3226 but differs in its guaranteed speed rating. The MAX3225 serves as the high-speed counterpart within the standard dual-driver lineup.

Replacement Considerations

Public confirmed substitute part numbers include MAX3225EUP and MAX3225EUP+. Verify that any replacement maintains the same 20-TSSOP pinout and electrical characteristics for direct board-level interchangeability.
