MAX3232EEUP+G1Z

Overview

The MAX3232EEUP+G1Z is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3V to 5.5V supply and includes two drivers and two receivers with ±15kV IEC ESD protection. The device supports data rates up to 250kbit/s and features a typical standby current of 300μA. It utilizes four external 0.1μF capacitors for charge pump operation. The component is housed in a 16-pin TSSOP package (PW) measuring 5mm x 6.4mm, suitable for surface-mount applications.

Feature Summary

• Provides full-duplex communication between asynchronous controllers and serial-port connectors
• Integrates dual charge-pump circuitry for true RS-232 voltage levels from low-voltage supplies
• Includes enhanced electrostatic discharge protection on all serial-port connection pins

Applications

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

Procurement Notes

Verify the specific suffix 'G1Z' against official manufacturer documentation to confirm environmental compliance and lead-free status. Confirm that the 16-TSSOP package dimensions match the design footprint requirements. Ensure the selected variant meets the required operating temperature range for the intended application environment before finalizing procurement.

Selection Notes

Select this component when designing systems requiring robust RS-232 interfaces with high ESD immunity. It is suitable for 3.3V and 5V logic systems needing low power consumption. Verify compatibility with existing PCB layouts designed for the PW package. Consider thermal resistance characteristics if multiple units are placed closely together on the board.

Part Context

This part belongs to the MAX3232E family of multichannel RS-232 line drivers and receivers. It shares functional similarities with other Maxim Integrated transceivers but offers specific pinout and performance characteristics. The device is widely used in legacy serial communication interfaces where reliability and low power are critical design constraints.

Replacement Considerations

The SNx5C3232 is identified as a pin-compatible alternative offering higher speed capabilities at 1Mbit/s. Verify electrical parameter compatibility and package alignment before substituting. Consult official cross-reference guides to ensure functional equivalence for specific system requirements.
