MAX3232EIPWG4

Overview

The MAX3232EIPWG4 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 on a single 3V to 5.5V supply and supports data rates up to 250kbit/s with a maximum slew rate of 30V/μs. It provides ±15kV IEC ESD protection on serial-port connection pins, including ground. Typical standby current is 300μA, and it requires four external 0.1μF capacitors for the charge pump.

Feature Summary

• Automotive qualification meeting AEC-Q100 standards
• Integrated dual charge-pump circuit for single-supply operation
• Robust ±15kV IEC electrostatic discharge protection
• Compatible with 5V logic inputs when powered by 3.3V

Applications

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

Procurement Notes

Verify the specific ordering suffix against the latest TI Package Option Addendum to confirm material type, lead finish, and moisture sensitivity level. Ensure the component status is listed as Active Production before finalizing procurement plans. Cross-reference the part marking code to validate authenticity and traceability during incoming inspection.

Selection Notes

Select this component for designs requiring automotive reliability and high ESD tolerance at serial interfaces. It serves as a direct pin-compatible alternative to standard catalog versions like the MAX3232E. Consider the 16-pin TSSOP footprint constraints and verify that the required external capacitor values align with the specific operating voltage conditions.

Part Context

This device belongs to the MAX3232 family of multichannel RS-232 line drivers and receivers. The 'E' designation indicates extended temperature performance, while the 'Q1' suffix denotes automotive qualification. It shares functional similarities with other low-power RS-232 transceivers but is distinguished by its specific automotive grade certification and robust ESD protection capabilities.

Replacement Considerations

The standard catalog version MAX3232E is functionally compatible but lacks automotive qualification. For higher-speed requirements, consider the SNx5C3232 series, which offers pin compatibility and 1Mbit/s data rates.
