MAX3232EEWE+

Overview

The MAX3232EEWE+ is a dual-channel RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3.0V to 5.5V supply and supports data rates up to 250kbit/s. The device integrates two drivers and two receivers with ±15kV IEC ESD protection on serial-port connection pins. It utilizes a dual charge-pump circuit requiring four external capacitors to generate the necessary RS-232 voltage levels. The component is housed in a 16-pin SO-Wide package.

Feature Summary

• Integrates dual line drivers and dual line receivers for full-duplex communication
• Includes built-in dual charge-pump circuitry eliminating the need for negative supply voltages
• Provides ±15kV IEC electrostatic discharge protection on all serial-port connection pins

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact package dimensions, temperature range, and environmental compliance status. Confirm current production status and availability through authorized distribution channels before initiating procurement processes.

Selection Notes

Select this component when designing interfaces between asynchronous communication controllers and serial-port connectors using 3V or 5V logic supplies. Ensure the application requires full-duplex operation and benefits from integrated ESD protection without requiring external level-shifting components.

Part Context

This part belongs to the MAX3232E family of low-power RS-232 transceivers designed for portable and industrial applications. It serves as a standard interface solution for converting TTL/CMOS logic levels to RS-232 standards while maintaining compatibility with various microcontroller architectures.

Replacement Considerations

The SNx5C3232 is identified as a pin-compatible alternative high-speed device offering 1Mbit/s data rates. Verify functional equivalence and electrical characteristics against the original datasheet specifications before implementing any substitution.
