MAX3232EIPWRG4

Overview

The MAX3232EIPWRG4 is an automotive-grade RS-232 transceiver manufactured by Texas Instruments. It integrates two line drivers, two receivers, and a dual charge-pump circuit within a 16-pin TSSOP package. The device operates from a single 3V to 5.5V supply and supports data rates up to 250kbit/s with a maximum slew rate of 30V/μs. It features ±15kV IEC ESD protection on serial-port connection pins and meets AEC-Q100 standards for automotive applications. Electrical characteristics include a typical standby current of 300μA and receiver hysteresis of 0.3V.

Feature Summary

• Qualified for automotive applications meeting AEC-Q100 standards
• Provides ±15kV IEC ESD protection on all serial-port connection pins including ground
• Accepts 5V logic inputs while operating with a 3.3V supply voltage
• Pin-compatible with alternative high-speed pin-compatible devices

Applications

• Industrial PCs
• Wired networking
• Data center and enterprise computing
• Battery-powered systems
• Notebooks and handheld equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm material type, lead finish, and moisture sensitivity level ratings. Ensure the component status matches production requirements and check for any recent packaging or assembly changes documented in product notifications.

Selection Notes

Select this component when automotive qualification and robust ESD protection are required for RS-232 interfaces. It is suitable for designs needing 5V tolerance on logic inputs despite lower supply voltages. Verify that the external capacitor values align with the specific supply voltage used in the application circuit.

Part Context

This part belongs to the MAX3232E-Q1 family of automotive RS-232 transceivers. It shares functional similarities with catalog versions like the MAX3232E but includes specific automotive reliability qualifications. The 'G4' suffix indicates lead-free construction compliant with RoHS directives.

Replacement Considerations

Catalog version MAX3232E serves as a non-automotive equivalent. High-speed alternative SNx5C3232 offers pin compatibility. TRS3232EIDR provides similar functionality in a SOIC package.
