MAX3245EETX+G071

Overview

The MAX3245EETX+G071 is a fully compliant RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features three drivers and five receivers, supporting full-duplex communication at data rates up to 1Mbps. The device operates on a single +3.0V to +5.5V supply and incorporates AutoShutdown Plus technology to achieve a typical supply current of 1μA during inactivity. It includes dual charge pumps requiring only four small capacitors for operation. The component provides ±15kV ESD protection via the Human Body Model and IEC 1000-4-2 standards. It is housed in a 36-pin TQFN package with an exposed pad and supports an operating temperature range from -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 voltage rails using minimal external capacitance.
• Enhanced electrostatic discharge protection ensures robustness against high-voltage static events.
• Dedicated noninverting receiver output allows continuous monitoring of line activity.

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 ordering suffix G071 against official manufacturer documentation to confirm exact packaging and RoHS compliance status. Confirm availability through authorized distributors as lead times may vary. Ensure the procurement channel sources genuine components to maintain signal integrity and reliability specifications.

Selection Notes

Select this component for applications requiring multiple transmitter and receiver channels within a compact footprint. The 1Mbps data rate suits high-speed serial communications such as ISDN modem interfacing. Verify that the system design accommodates the required external capacitor values for the charge pump circuitry to ensure stable voltage generation across the operating temperature range.

Part Context

This part belongs to the MAX3245E family of RS-232 transceivers designed for low-power, space-constrained environments. It shares core architectural features with the MAX3224E, MAX3225E, and MAX3244E series but distinguishes itself through its specific driver and receiver count configuration. The device represents Maxim Integrated's approach to balancing performance with extreme power efficiency in portable electronics.

Replacement Considerations

Direct functional substitutes include the MAX3245EETX and MAX3245EETX+T. These variants share identical electrical characteristics and pinouts. Verify package compatibility and thermal requirements when transitioning between different supplier lot markings or tape-and-reel versus tube packaging options.
