MAX232ECPE+

Overview

The MAX232ECPE+ is a single-supply RS-232 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a +4.5V to +5.5V supply with a typical current of 10mA. The device integrates two drivers and two receivers, supporting full-duplex communication at data rates up to 120kbps. It features ±15kV ESD protection via the Human Body Model. The component utilizes an internal charge pump requiring four external capacitors to generate the necessary voltage levels for RS-232 signaling. It is housed in a 16-pin Plastic DIP package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrated high electrostatic discharge protection rated at ±15kV for robust operation in harsh environments.
• Built-in dual charge-pump circuitry eliminates the requirement for external bipolar power supplies.
• Provides TTL/CMOS compatible logic levels through tight receiver input thresholds.

Applications

• Battery-powered equipment
• Hand-held equipment
• Portable diagnostics equipment

Procurement Notes

Verify the specific suffix 'CPE+' corresponds to the commercial temperature range and plastic DIP package configuration. Confirm that the ordering information matches the manufacturer's latest documentation to ensure compatibility with the intended application requirements.

Selection Notes

Select this component when a single +5V supply is available and ESD protection is critical. Ensure the design accommodates four external capacitors for the charge pump. Verify that the 120kbps data rate meets system requirements and that the 16-pin DIP footprint fits the PCB layout constraints.

Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers. The 'E' designation indicates enhanced ESD protection capabilities compared to standard versions. The 'C' suffix specifies the commercial operating temperature range, while 'P' denotes the plastic DIP package style.

Replacement Considerations

The MAX232EESE+ serves as a direct replacement offering extended temperature range (-40°C to +85°C) and surface mount packaging. Other family members like the MAX202E or MAX241E provide different driver/receiver counts but share similar operational principles.
