MAX220EWE+T

Overview

The MAX220EWE+T is a +5V-powered, multichannel RS-232 driver and receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 200kbps. The device features two drivers and two receivers in full-duplex mode, housed in a 16-pin Wide SOIC package. It functions across an operating temperature range of -40°C to +85°C with a typical supply current of 10mA under load.

Feature Summary

• Integrates internal charge-pump circuitry to generate required ±10V levels from a single +5V supply, eliminating the need for external bipolar power sources.

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 communication networks
• Portable diagnostic equipment requiring low-power serial connectivity

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing this component. Confirm that the 'E' designation corresponds to the industrial temperature grade (-40°C to +85°C). Ensure the '+T' suffix aligns with RoHS compliance requirements for your assembly process.

Selection Notes

Select this part for applications requiring standard RS-232 signaling without external high-voltage supplies. Compare against MAX232 variants if different pinouts or capacitor requirements are needed. Verify that the 16-pin Wide SOIC footprint fits the target PCB layout constraints.

Part Context

This component belongs to the MAX220–MAX249 family of line drivers/receivers designed for EIA/TIA-232E and V.28/V.24 interfaces. The family offers various channel counts and packages, with the MAX220 specifically providing dual drivers and receivers optimized for general-purpose serial communication tasks.
