MAX3232ECAE+TGA8

Overview

The MAX3232ECAE+TGA8 is an automotive-grade RS-232 transceiver manufactured by Texas Instruments. It features two drivers and two receivers, supporting data rates up to 250 kbit/s with a maximum slew rate of 30 V/μs. The device operates from a single 3V to 5.5V supply and includes a dual charge-pump circuit requiring four external 0.1μF capacitors. It provides ±15kV IEC ESD protection on serial-port connection pins and accepts 5V logic inputs when powered by a 3.3V supply. The component is housed in a 16-pin TSSOP (PW) package.

Feature Summary

• Automotive qualification meeting AEC-Q100 standards
• Integrated dual charge pump for single-supply operation
• Robust ±15kV IEC electrostatic discharge protection
• Compatible with 5V logic signals at 3.3V supply voltage

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 manufacturer's current Package Option Addendum to confirm the exact tape-and-reel specifications and moisture sensitivity level. Ensure the procurement channel sources parts directly from authorized distributors to guarantee authenticity and traceability for automotive compliance requirements.

Selection Notes

Select this component for designs requiring automotive reliability and robust ESD immunity. It serves as a direct pin-compatible alternative to high-speed variants like the SNx5C3232. Verify that the application does not exceed the 250 kbit/s signaling limit or require shutdown functionality, which is absent in this specific variant.

Part Context

This part belongs to the MAX3232E family of multichannel RS-232 line drivers and receivers. It is specifically designated for automotive applications, distinguishing it from standard commercial versions through rigorous qualification processes. The device maintains electrical compatibility with the TIA/EIA-232-F standard while offering enhanced durability for harsh environments.

Replacement Considerations

The catalog version MAX3232E is a non-automotive equivalent. For higher speed requirements, the SNx5C3232 offers pin-compatible performance up to 1Mbit/s. Direct substitution requires confirming that the replacement meets the specific temperature range and reliability standards of the target system.
