MAX3232EEUE+

Overview

The MAX3232EEUE+ is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 16-pin TSSOP package. It operates on 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. It requires four external 0.1μF capacitors for its dual charge-pump circuitry. Typical standby current is 300μA at VCC = 3.3V or 5V. Operating temperature range is -40°C to +85°C.

Feature Summary

• Integrated dual charge pump enables operation from a single low-voltage supply using small external capacitors.
• Provides enhanced electrostatic discharge protection rated at ±15kV for both human body mode and IEC61000-4-2 air discharge methods.
• Accepts 5V logic inputs while operating with a 3.3V supply voltage.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm exact packaging and environmental compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the component meets RoHS standards required for your assembly process before finalizing procurement orders.

Selection Notes

Select this component when designing serial communication interfaces requiring robust ESD protection and low power consumption. Verify that the system operates within the specified 3V to 5.5V supply range. Ensure adequate board space is allocated for the four required external charge-pump capacitors during the layout phase.

Part Context

This part belongs to the MAX3232 family of low-power RS-232 transceivers designed for portable applications. It maintains pin compatibility with industry-standard MAX232 devices while offering improved performance characteristics such as lower supply current and enhanced ESD tolerance suitable for modern electronic environments.

Replacement Considerations

The SNx5C3232 is identified as a high-speed pin-compatible alternative device. Verify functional equivalence regarding data rate requirements and electrical specifications before substituting components in existing designs.
