MAX232CEAWE+T

Overview

The MAX232CEAWE+T is a dual driver and receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. Designed for single +5V power supply operation, it integrates charge pump circuitry to generate internal voltage rails, requiring only four external capacitors. The device supports full-duplex communication with a data rate of up to 120 kb/s. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a typical operating current of 8 mA. The component is housed in a 16-pin SOIC-Wide package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual drivers and receivers for full-duplex RS-232 communication
• Utilizes internal charge pump to eliminate need for external negative voltage supplies
• Operates on a single +5V power source with minimal external capacitance requirements

Applications

• Serial port connections between microcontrollers and personal computers
• Modem interfacing in embedded systems
• Industrial control equipment requiring EIA/TIA-232-E compliance

Procurement Notes

Verify the specific suffix 'EAWE' against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets required environmental specifications for the intended application environment before integration into final designs.

Selection Notes

Select this component when designing systems requiring standard RS-232 signaling with a single +5V supply. It serves as a suitable replacement for legacy MAX232 variants where extended temperature ranges are necessary. Confirm that the 120 kb/s data rate suffices for the target application's throughput requirements.

Part Context

This part belongs to the MAX232 family of multi-channel RS-232 drivers and receivers. The series was originally developed to simplify serial communication by integrating level shifting and voltage generation into a single IC. The MAX232CEAWE+T represents an enhanced version offering improved performance over standard commercial grade parts.
