MAX232CEAWE+

Overview

The MAX232CEAWE+ is a dual driver and dual receiver RS-232 transceiver operating from a single +5V supply. It features an integrated charge pump generating ±10V levels, eliminating the need for external bipolar supplies. The device supports data rates up to 200 kbps with full duplex communication. It operates within a commercial temperature range of 0°C to +70°C and utilizes a 16-pin Wide SOIC package.

Feature Summary

• Integrated charge pump circuitry eliminates the need for bipolar ±12V power supplies
• Enables single +5V supply operation for simplified system design
• Provides full-duplex communication via two independent drivers and receivers

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 network connections
• Portable diagnostics equipment requiring low power consumption

Procurement Notes

Verify the specific suffix 'C' confirms the 0°C to +70°C commercial temperature rating. Confirm the 'E' indicates the Wide SOIC package variant. Ensure the '+' suffix denotes lead-free compliance. Cross-reference the manufacturer's current production status as older variants may be discontinued.

Selection Notes

Select this component when a standard RS-232 interface is required without external voltage generation. Compare against MAX232AEWE+ if extended industrial temperature ranges (-40°C to +85°C) are necessary. Verify that the 200 kbps data rate meets the application requirements compared to lower-speed alternatives.

Part Context

This part belongs to the MAX220–MAX249 family of +5V-powered multichannel RS-232 drivers and receivers. The MAX232 specifically provides two drivers and two receivers in a compact form factor. It is designed for applications where space is limited and ±12V supplies are unavailable.

Replacement Considerations

The MAX232AEWE+ serves as a direct functional replacement offering an extended temperature range. The MAX232CWE is a compatible alternative using a narrow SOIC package instead of the wide variant.
