MAX3232EEWE+G1Z

Overview

The MAX3232EEWE+G1Z is a dual RS-232 transceiver manufactured by Analog Devices/Maxim Integrated. It operates from a single 3V 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 requires four external 0.1μF capacitors for the charge pump circuit. The component is housed in a 16-SOIC (Wide) package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides full RS-232 signal conversion between TTL/CMOS logic levels and serial port connectors
• Integrates dual charge-pump circuitry to generate required voltage swings from a single low-voltage supply
• Includes robust electrostatic discharge protection rated at ±15kV on interface pins

Applications

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

Procurement Notes

Verify current availability status as the part may be discontinued or subject to limited supply conditions. Confirm that the specific SOIC-16 Wide package variant matches the design requirements. Ensure compliance with RoHS directives if applicable to the target market. Validate that the supplier provides genuine components with traceable documentation.

Selection Notes

Select this component when designing interfaces requiring dual RS-232 channels without shutdown functionality. Verify that the system operates within the specified 3V to 5.5V voltage range. Ensure the PCB layout accommodates the necessary four external capacitors for the charge pump. Confirm that the 250kbit/s data rate meets the application's communication speed requirements.

Part Context

This device belongs to the MAX3232E series of low-power RS-232 transceivers. It serves as a standard interface solution for connecting microcontrollers and UARTs to serial ports. The EE suffix indicates extended temperature ratings and enhanced ESD protection compared to commercial variants. It is widely used in legacy serial communication designs.

Replacement Considerations

The SNx5C3232 is identified as a pin-compatible alternative offering higher speed capabilities. Verify compatibility regarding package dimensions and electrical characteristics before substitution.
