MAX3232EIPWR

Overview

The MAX3232EIPWR is a dual driver and receiver RS-232 transceiver manufactured by Texas Instruments. It operates on a single 3V to 5.5V supply voltage and supports data rates up to 250kbit/s. The device incorporates a dual charge-pump circuit requiring four external 0.1μF capacitors. It provides ±15kV IEC ESD protection on serial-port connection pins, including ground. The component features two drivers and two receivers for full-duplex communication. It operates within an industrial temperature range of -40°C to +85°C and draws a typical standby current of 300μA.

Feature Summary

• Integrated dual charge-pump circuit enables operation from a single low-voltage power supply using minimal external components.
• Provides robust ±15kV IEC electrostatic discharge protection across all serial port connection pins to enhance system reliability.
• Accepts 5V logic inputs while operating with a 3.3V supply, facilitating direct interfacing with various microcontroller architectures.

Applications

• Industrial PCs
• Wired networking equipment
• Data center and enterprise computing systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, temperature grade, and packaging format. Ensure the selected variant matches the required application environment and regulatory compliance standards before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring reliable RS-232 communication in environments subject to electrical noise or static discharge. The wide supply voltage range allows compatibility with both 3.3V and 5V logic families without additional level shifting circuitry.

Part Context

This part belongs to the MAX3232 family of multichannel RS-232 line drivers and receivers. It serves as a standard interface solution for connecting asynchronous communication controllers to serial port connectors in embedded and industrial applications.

Replacement Considerations

The SNx5C3232 series is a pin-compatible alternative offering higher data rates up to 1Mbit/s. Verify that the increased speed requirements are met if considering this substitution.
