MAX239CWG+

Overview

The MAX239CWG+ is a +5V-powered, multichannel RS-232 transceiver featuring three drivers and five receivers. It operates on a single +5V supply with an integrated charge pump generating ±10V to ±13.2V levels. The device supports data rates up to 120 kbps and functions within a commercial temperature range of 0°C to +70°C. It utilizes a 24-pin SOIC package for surface-mount installation.

Feature Summary

Integrates dual charge-pump circuitry to generate required RS-232 voltage swings from a single +5V source
Provides three independent transmitter channels and five independent receiver channels
Supports full-duplex communication compliant with EIA/TIA-232E standards

Applications

Multidrop RS-232 networks
Portable diagnostics equipment
Interface translation between TTL/CMOS logic and RS-232 serial buses

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required package type and temperature rating. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a design requires multiple serial ports without external bipolar power supplies. The integrated charge pump eliminates the need for discrete capacitors in some configurations, though standard operation requires external timing capacitors. Verify that the 120 kbps data rate meets system requirements and that the 24-pin footprint fits the PCB layout constraints.

Part Context

This device belongs to the MAX220–MAX249 family of line drivers and receivers designed for EIA/TIA-232E applications. The family offers various channel counts and packages to optimize board space. The MAX239 variant specifically provides a high channel count suitable for complex serial communication interfaces requiring multiple simultaneous connections.

Replacement Considerations

Compatible substitutes within the same family include the MAX232CPE and MAX242CWE. Verify that replacement parts maintain identical driver/receiver counts and package dimensions. Confirm that any alternative device supports the same +5V single-supply operation and charge pump functionality.
