MAX3227ECTE+

Overview

The MAX3227ECTE+ is a single-channel, full-duplex RS-232 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single +3.0V to +5.5V supply and achieves a typical supply current of 1μA through AutoShutdown Plus technology. The device guarantees data rates up to 1Mbps and features ±15kV ESD protection compliant with IEC standards. It utilizes a dual charge pump requiring four 0.1μF capacitors for operation. The component is housed in a 16-pin TQFN-EP package and supports an operating temperature range from 0°C to +70°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 without external transformers.
• Enhanced electrostatic discharge protection ensures robustness against high-voltage static events.

Applications

• Notebook, Subnotebook, and Palmtop Computers
• Cellular Phones
• Battery-Powered Equipment
• Hand-Held Equipment
• Peripherals

Procurement Notes

Verify the specific suffix 'ECTE+' corresponds to the required TQFN-EP package and commercial temperature grade during sourcing. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the ordering information matches the exact pinout and thermal pad requirements for your PCB layout design.

Selection Notes

Select this part for applications requiring a single transmitter and receiver with high-speed 1Mbps capability. Consider alternative models within the MAX3224E-MAX3227E family if different channel counts or lower data rate specifications are sufficient for the system design.

Part Context

This component belongs to the MAX3224E/MAX3225E/MAX3226E/MAX3227E series of low-power RS-232 transceivers. These devices share common architectural features such as the AutoShutdown Plus circuitry and dual charge pump topology, differing primarily in channel count and guaranteed data rates.
