MAX3232EWE+T

Overview

The MAX3232EWE+T is a low-power, true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 3V to 5.5V supply and supports data rates up to 250 kbit/s. The device integrates two drivers and two receivers in a 16-pin SO-Wide package. It utilizes a dual charge-pump circuit requiring only four external 0.1μF capacitors. Typical supply current is 1 mA at VCC = 3.3V or 5V. Operating temperature range spans from -40°C to +85°C.

Feature Summary

• Integrates dual charge-pump circuitry for generating RS-232 voltage levels from a single low-voltage supply
• Provides full-duplex communication with two independent drivers and two receivers
• Maintains compatibility with industry-standard pinouts and functionality

Applications

• Industrial PCs
• Wired networking equipment
• Data center and enterprise computing systems

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and reel specifications. Confirm that the component meets all required environmental standards for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when a standard RS-232 interface is required within a 3V to 5.5V power domain. Ensure the application design accommodates the necessary external capacitor count for the charge pump circuit. Verify that the 250 kbit/s signaling rate satisfies the system's throughput requirements.

Part Context
