MAX3232EEPE+

Overview

The MAX3232EEPE+ is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers, operating with a single 3V to 5.5V supply voltage. The device supports data signaling rates up to 250kbit/s and includes ±15kV IEC ESD protection on all serial-port connection pins. It utilizes a dual charge-pump circuit requiring four external capacitors (typically 4 × 0.1μF) to generate the necessary internal voltages. The component operates within an industrial temperature range of -40°C to +85°C and is housed in a 16-pin DIP package.

Feature Summary

• Dual charge-pump architecture enables operation from a single low-voltage power supply without requiring negative voltage rails.
• Integrated electrostatic discharge protection rated at ±15kV IEC standard across all serial port interface pins.
• Full compliance with TIA/EIA-232-F and ITU v.28 communication standards for reliable asynchronous data transmission.
• Low standby current consumption designed to extend battery life in portable and handheld electronic equipment.

Applications

• Industrial PCs and wired networking systems
• Battery-powered mobile devices and handheld equipment
• Data center and enterprise computing infrastructure

Procurement Notes

Verify the specific suffix 'EPE+' against official manufacturer documentation to confirm the exact package type and lead finish. Confirm that the intended application environment falls within the specified -40°C to +85°C operating temperature range. Ensure the design accommodates the required four external capacitors for the charge pump circuitry as detailed in the datasheet.

Selection Notes

Select this component when a full-duplex RS-232 interface is required for 3V or 5V logic systems. It is suitable for designs needing robust ESD protection on serial lines. Consider alternative pin-compatible high-speed devices if data rates exceeding 250kbit/s are necessary. Verify that the physical footprint matches the available 16-pin DIP housing constraints.

Part Context

This device belongs to the MAX3232 family of multichannel RS-232 line drivers and receivers. It serves as a bridge between microcontrollers using TTL/CMOS logic levels and standard serial port connectors. The EEPE+ designation indicates a specific variant within the broader Maxim Integrated product line focused on low-power, single-supply applications.

Replacement Considerations

The SNx5C3232 series is identified as a pin-compatible alternative offering higher data rates up to 1Mbit/s. Verify mechanical compatibility and electrical specifications before substituting any other RS-232 transceiver components.
