MAX3245EEAI

Overview

The MAX3245EEAI+ is a full-duplex RS-232 transceiver featuring three drivers and five receivers. It supports data rates up to 1Mbps and operates on a single +3.0V to +5.5V supply. The device incorporates AutoShutdown Plus technology, reducing supply current to 1μA during inactivity. It provides ±15kV ESD protection across air-gap, contact discharge, and human body models. The component utilizes a dual charge pump requiring four small capacitors for voltage generation. It is housed in a 28-pin SSOP package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption when the interface is idle or disconnected.
• Integrated dual charge pump generates internal positive and negative voltages from a single low-voltage supply.
• Enhanced electrostatic discharge protection ensures robustness against high-voltage static events.
• Dedicated R2OUTB output allows continuous monitoring of receiver activity even when primary outputs are disabled.

Applications

• Notebook, subnotebook, and palmtop computers
• Cellular phones and battery-powered equipment
• Hand-held devices and peripherals
• Printers and automotive systems

Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature range of -40°C to +85°C. Confirm the '+' suffix indicates lead-free and RoHS compliance status. Ensure the 'AI' designation matches the required 28-pin SSOP physical footprint. Cross-reference the manufacturer's latest documentation to confirm current production status and availability.

Selection Notes

Select this model over the MAX3244E variant when applications require data transmission speeds up to 1Mbps rather than the 250kbps limit. Choose this part if the design requires five receiver inputs alongside three transmitter outputs. Verify that the system can accommodate the external capacitor requirements for the internal charge pump circuitry.

Part Context

This component belongs to the MAX3224E through MAX3245E family of RS-232 transceivers. It shares core architectural features with siblings like the MAX3244E but differs in guaranteed maximum data rate. The family utilizes Maxim Integrated's proprietary AutoShutdown Plus technology to optimize power efficiency in portable electronics.
