MAX232CAWE+T

Overview

The MAX232CAWE+T is a dual driver/receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V power supply, utilizing an internal charge pump to generate the required ±10V levels for EIA/TIA-232-E communication standards. The device features two drivers and two receivers supporting full-duplex data transmission at speeds up to 200 kb/s. It functions within a supply voltage range of 4.5 V to 5.5 V with a typical operating current of 10 mA. The component is housed in a 16-pin SOIC package and supports surface mount installation. It operates reliably across a commercial temperature range from 0°C to +70°C.

Feature Summary

• Integrates a charge pump circuit to enable RS-232 level shifting using only a single +5V power source
• Provides bidirectional communication through two independent drivers and two receivers
• Supports standard EIA/TIA-232-E protocol for serial data exchange

Applications

• EIA/TIA-232-E and V.28/V.24 communications interface applications
• Embedded systems requiring TTL/CMOS to RS-232 level conversion
• Industrial control equipment serial ports

Procurement Notes

Verify the specific suffix 'CAWE' against official manufacturer documentation to confirm the exact grade and packaging configuration. Ensure the component matches the required commercial temperature range and SOIC-16 footprint for your design. Cross-reference the datasheet revision history to confirm pinout compatibility with existing layouts.

Selection Notes

Select this component when a single +5V supply is available and high-speed data rates are not required. It serves as a direct replacement for legacy MAX232 designs needing commercial grade performance. Consider alternative models if extended temperature ranges or lower power consumption are necessary for the target application environment.

Part Context

This part belongs to the foundational MAX232 family, which established the architecture for single-supply RS-232 transceivers. It represents the commercial grade variant within the broader series that includes industrial and extended temperature options. The device remains a standard reference for basic serial interface implementations in embedded hardware.

Replacement Considerations

Compatible substitutes include the MAX232ACWE+T and MAX232CWE+T. Verify that any replacement maintains the same 16-SOIC package dimensions and electrical characteristics to ensure board-level interchangeability without redesign.
