MAX232EESE+

Overview

The MAX232EESE+ is a dual transmitter/receiver RS-232 transceiver designed for single +5V supply operation. It integrates charge pump circuitry to generate internal ±10V levels, eliminating the need for external bipolar supplies. The device provides two drivers and two receivers with full duplex communication capability. It supports data rates up to 120 kbps and operates within a supply voltage range of 4.5 V to 5.5 V. Typical supply current is 10 mA at +5 V. The component features high electrostatic discharge protection rated at ±15 kV via the Human Body Model. It is housed in a 16-pin Narrow SO package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrated charge pump eliminates requirement for external bipolar power supplies
• High ESD tolerance protects against ±15kV human body model discharges
• Single +5V supply operation reduces system complexity and cost
• TTL and CMOS compatible logic input and output thresholds

Applications

• Battery-powered equipment requiring low power interface solutions
• Hand-held diagnostic tools and portable measurement devices
• Portable computers and mobile communication systems

Procurement Notes

Verify the specific suffix 'ESE+' corresponds to the narrow SOIC-16 package and industrial temperature grade (-40°C to +85°C). 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 requiring robust RS-232 connectivity under single-supply constraints. Ensure external capacitors are sized appropriately for the charge pump circuit as specified in the datasheet. Consider thermal dissipation limits if operating near maximum ambient temperatures or load conditions.

Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers manufactured by Analog Devices (formerly Maxim Integrated). The 'E' designation indicates enhanced ESD protection capabilities compared to standard variants. The MAX232 variant specifically offers two drivers and two receivers suitable for basic serial communication interfaces.

Replacement Considerations

Direct pin-compatible substitutes include other members of the MAX232E family such as MAX232ECSE+ for commercial temperature ranges. Verify package dimensions and electrical characteristics match before substitution.
