MAX3232ECWE+

Overview

The MAX3232ECWE+ is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3V to 5.5V supply and supports data rates up to 250kbps. The device integrates two drivers and two receivers within a 16-SOIC package. Key electrical parameters include a typical supply current of 1mA, a propagation delay of 0.15us, and an operating temperature range of 0°C to +70°C. It features 15kV ESD protection on I/O pins.

Feature Summary

• Integrates dual line drivers and dual line receivers for full-duplex communication
• Provides enhanced electrostatic discharge (ESD) protection rated at 15kV
• Operates efficiently from a single low-voltage power supply

Applications

• Industrial PCs
• Wired networking equipment
• Battery-powered portable systems

Procurement Notes

Verify the specific suffix 'ECWE+' against official manufacturer documentation to confirm the commercial temperature grade and SOIC package variant. Confirm RoHS compliance status through the latest datasheet revision history. Ensure the component source is authorized to avoid counterfeit parts, as this series has multiple automotive and industrial variants with distinct qualification levels.

Selection Notes

Select this component when a dual-channel RS-232 interface is required for 3V or 5V logic systems. Verify that the 250kbps maximum data rate meets application timing requirements. Compare the 0°C to +70°C commercial temperature range against environmental conditions; consider the EE variant if extended -40°C to +85°C operation is necessary.

Part Context

This part belongs to the MAX3232E family of True RS-232 transceivers designed for low-power applications. It serves as a standard interface solution for connecting microcontrollers or UARTs to serial ports. The ECWE+ designation specifically identifies the commercial grade version in a wide SOIC package, distinguishing it from automotive or extended temperature counterparts.
