MAX209CWG

Drivers, Receivers, Transceivers Overview

The MAX209CWG is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and requires external capacitors for its internal charge pump circuitry. The device integrates two drivers and five receivers, supporting data rates up to 120kbps. It utilizes a 24-pin Wide SOIC package and functions within an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates dual voltage converters to generate required RS-232 signal levels from a single power source
• Includes pullup resistors on driver inputs to simplify unused channel management
• Provides receiver outputs with defined logic states when inputs are open or grounded

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power serial communication
• Handheld devices utilizing standard asynchronous interfaces
• Portable diagnostic equipment needing reliable data transmission

Drivers, Receivers, Transceivers Procurement Notes

Verify the component status as discontinued through official manufacturer channels before procurement planning. Confirm that the CWG suffix corresponds to the correct Wide SOIC package variant and commercial temperature rating. Ensure all necessary external components are sourced separately to complete the design implementation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a system requires multiple receiver lines alongside dual transmission paths. The integrated charge pump eliminates the need for external bipolar supplies. Verify that the application environment remains within the specified commercial temperature limits during operation.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209 family of RS-232 transceivers designed for single-supply applications. The family shares common architectural features including integrated charge pumps and TTL/CMOS compatible inputs. Variations within the series differ primarily in the number of drivers, receivers, and specific control pin configurations.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the MAX201CWG+ and HIN239CBZ. These alternatives offer similar interface capabilities but may require verification of pin compatibility and electrical specifications against the original design requirements.
