MAX3232EEUE

Overview

The MAX3232EEUE+ is a dual driver/receiver RS-232 transceiver in a 16-pin TSSOP package. It operates from a single 3V to 5.5V supply and supports data rates up to 250kbit/s. The device includes two drivers and two receivers with ±15kV IEC ESD protection on serial-port pins. Typical supply current is 300µA, requiring four 0.1µF external capacitors for the charge pump.

Feature Summary

• Dual channel RS-232 transceiver with integrated charge pump
• ±15kV IEC ESD protection on serial port connection pins
• Low standby current of 300µA typical
• Compatible with 3.3V and 5V logic systems

Applications

• Industrial PCs
• Wired networking equipment
• Data center and enterprise computing systems
• Battery-powered portable devices

Procurement Notes

Verify the specific suffix 'EUE+' against the manufacturer's official ordering guide to confirm the exact package type (TSSOP) and temperature range. Confirm RoHS compliance status directly with the supplier documentation before procurement.

Selection Notes

Select this component when interfacing UARTs to RS-232 connectors in space-constrained designs. Ensure the application requires only two channels and does not exceed the 250kbit/s signaling rate limit defined in the electrical characteristics.

Part Context

This part belongs to the MAX3232 family of low-power RS-232 transceivers. It serves as a pin-compatible alternative to older industry standards like the MAX232, offering improved power efficiency and higher ESD robustness while maintaining functional compatibility.

Replacement Considerations

The SNx5C3232 series is documented as a high-speed pin-compatible alternative. Verify that the replacement meets the specific voltage and ESD requirements of the target design.
