MAX3232ECSE+

Overview

The MAX3232ECSE+ is a multichannel RS-232 line driver and receiver manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers with ±15kV IEC ESD protection on all serial-port connection pins, including ground. The device operates from a single 3V to 5.5V supply using a dual charge-pump circuit requiring four external capacitors. It supports data signaling rates up to 250kbit/s and meets TIA/EIA-232-F standards. The component is housed in a 16-pin SOIC-Narrow (SE) package.

Feature Summary

• Integrated dual charge-pump circuit enabling operation from a single low-voltage power supply without negative voltage generation.
• Built-in electrostatic discharge protection rated at ±15kV IEC standard across all serial port connection terminals.
• Full compatibility with asynchronous communication controllers for direct electrical interfacing with serial-port connectors.

Applications

• Industrial PCs
• Wired networking equipment
• Battery-powered portable systems

Procurement Notes

Verify the specific suffix 'ECSE+' against official manufacturer documentation to confirm exact package dimensions and temperature ratings. Ensure that the ordering information matches the required automotive or industrial specifications before finalizing procurement orders.

Selection Notes

Select this component when designing interfaces requiring robust ESD protection and low-power consumption for battery-operated devices. Confirm that the system logic levels are compatible with the specified input voltage ranges and that the available PCB space accommodates the required external capacitors for the charge pump.

Part Context

This part belongs to the MAX3232 family of true RS-232 transceivers designed for low-power applications. It serves as a bridge between microcontroller TTL/CMOS logic levels and standard RS-232 serial ports, commonly used in legacy interface designs where reliability and noise immunity are critical requirements.

Replacement Considerations

Consider SNx5C3232 variants for high-speed pin-compatible alternatives if higher data rates are required. Verify thermal performance and package footprint compatibility when substituting with other RS-232 transceivers from different manufacturers.
