MAX3232EEPE

Overview

The MAX3232EEPE+ is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3V to 5.5V supply and includes two drivers and two receivers. The device features ±15kV IEC ESD protection on all serial-port connection pins, including ground. It utilizes a dual charge-pump circuit requiring four external capacitors to generate the necessary RS-232 voltage levels. The component supports data signaling rates up to 250kbit/s with a maximum driver output slew rate of 30V/μs. It meets TIA/EIA-232-F and ITU v.28 standards and is available in a 16-pin DIP package.

Feature Summary

• Integrated dual charge-pump circuit enables operation from a single low-voltage power supply without requiring negative voltage rails.
• Provides enhanced electrostatic discharge protection rated at ±15kV IEC standard across all serial port interface pins.
• Delivers true RS-232 performance compliant with TIA/EIA-232-F and ITU v.28 communication standards.
• Supports full-duplex asynchronous communication with independent transmit and receive channels.

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature range. Confirm RoHS compliance status for environmental regulations. Ensure the supplier provides valid traceability documentation for the manufacturing lot. Cross-reference the manufacturer's current datasheet revision to confirm pinout and electrical specifications have not changed.

Selection Notes

Select this component when interfacing microcontrollers or UARTs with standard RS-232 connectors. Verify that the system operating voltage falls within the 3V to 5.5V range. Ensure sufficient board space is allocated for the four required external charge-pump capacitors. Consider the 250kbit/s data rate limit against application requirements.

Part Context

This device belongs to the MAX3232 family of multichannel RS-232 line drivers and receivers. It serves as a bridge between TTL/CMOS logic levels and RS-232 signal levels. The EEPE variant specifically denotes an extended industrial temperature range and a plastic DIP package format suitable for through-hole mounting.

Replacement Considerations

SNx5C3232 is a pin-compatible high-speed alternative offering 1Mbit/s data rates. SN65C3232 and SN75C3232 are compatible options provided by Texas Instruments. Verify that any substitute maintains the same package dimensions and capacitor requirements.
