MAX3245EETX+T

Overview

The MAX3245EETX+T is a fully compliant RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features three drivers and five receivers, supporting data rates up to 1Mbps. The device operates on a single +3.0V to +5.5V supply with an operating supply current of 1μA in AutoShutdown Plus mode. It includes ±15kV ESD protection on all inputs and outputs. The component utilizes a dual charge pump for voltage conversion and is housed in a 36-pin TQFN-EP package.

Feature Summary

• AutoShutdown Plus technology automatically reduces power consumption when the interface is idle or disconnected.
• Integrated dual charge pumps generate internal positive and negative voltages from a single low-voltage supply.
• Enhanced electrostatic discharge protection ensures robustness against high-voltage static events.

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging format and lead-free status. Confirm that the exposed pad (EP) variant matches the required thermal dissipation and footprint specifications for the target printed circuit board design.

Selection Notes

Select this model over the MAX3244E when a guaranteed 1Mbps data rate is required for high-speed applications such as ISDN modem communication. Ensure the system design accommodates the 36-pin TQFN footprint and provides adequate thermal relief for the exposed pad.

Part Context

This component belongs to the MAX32xxE family of RS-232 transceivers designed for portable electronics. It shares core architectural features with the MAX3224E through MAX3227E but offers a higher pin count to support additional serial lines within space-constrained mobile and handheld form factors.
