MAX232ECSE+

Overview

The MAX232ECSE+ is a single-supply RS-232 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of +4.5V to +5.5V and supports data rates up to 120kbps. The device integrates two drivers and two receivers, providing full-duplex communication capabilities. It utilizes an internal charge pump circuitry to generate the required ±10V levels from a single +5V source, eliminating the need for external bipolar supplies. The component features high electrostatic discharge protection rated at ±15kV via the Human Body Model. Designed for commercial temperature environments, it functions reliably between 0°C and +70°C. The unit is housed in a 16-pin Narrow SO package.

Feature Summary

• Integrated dual charge-pump voltage converters enable operation from a single +5V power supply without requiring external bipolar voltages.
• High robustness against electrostatic discharge with ±15kV Human Body Model protection on all RS-232 inputs and outputs.
• Receiver inputs feature tight logic thresholds that ensure compatibility with TTL and CMOS logic levels while maintaining RS-232 compliance.

Applications

• Battery-powered equipment requiring low-power serial communication
• Hand-held diagnostic tools and portable measurement devices
• Portable computers and notebook interfaces

Procurement Notes

Verify the specific suffix 'CSE+' corresponds to the narrow SOIC-16 package and the commercial 0°C to +70°C operating temperature range. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration into production designs.

Selection Notes

Select this component when designing systems that require standard RS-232 signaling but are constrained to a single +5V power rail. Ensure the application environment remains within the commercial temperature limits of 0°C to +70°C. Verify that the system does not require shutdown control functionality, as this specific variant lacks enable or shutdown pins.

Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers. These devices share a common architecture featuring integrated charge pumps and ESD protection. The MAX232E variant specifically provides two drivers and two receivers, distinguishing it from other family members like the MAX202E which shares similar electrical characteristics but may differ in pinout or packaging options.

Replacement Considerations

The MAX232EESE+ serves as a direct replacement offering identical electrical specifications but extended industrial temperature range capability (-40°C to +85°C).
