MAX3232EETE+

Overview

The MAX3232EETE+ is a dual driver and receiver RS-232 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single 3V to 5.5V supply and utilizes an internal dual charge pump with four external capacitors to generate RS-232 voltage levels. The device supports data rates up to 250kbit/s, features ±15kV IEC ESD protection, and includes a low standby current of 300μA typical. It is housed in a TSSOP-16 package.

Feature Summary

• Dual drivers and receivers for full-duplex communication
• Integrated dual charge pump requiring only four small external capacitors
• Robust ±15kV IEC ESD protection on all serial-port connection pins
• Low standby current consumption suitable for battery-powered applications

Applications

• Industrial PCs
• Wired networking equipment
• Battery-powered handheld devices

Procurement Notes

Verify the specific suffix 'EETE+' against official manufacturer documentation to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and supply voltage constraints before procurement.

Selection Notes

Select this component when a true RS-232 interface is needed from a 3.3V or 5V logic system without requiring negative voltage rails. Consider the 250kbit/s speed limit and TSSOP-16 footprint during PCB layout planning.

Part Context

This part belongs to the MAX3232 family of low-power RS-232 transceivers. It provides pin-to-pin compatibility with industry-standard MAX232 devices while offering improved performance characteristics such as lower power consumption and enhanced ESD protection capabilities.

Replacement Considerations

The SNx5C3232 is identified as a high-speed pin-compatible alternative within the same product family.
