MAX208CWG

Drivers, Receivers, Transceivers Overview

The MAX208CWG+ is a +5V RS-232 transceiver from the Analog Devices/MAXIM family, designed for single-supply operation using integrated charge pump circuitry. It features four drivers and four receivers with full duplex communication capability. The device operates at data rates exceeding 120kbps while maintaining ±5V EIA/TIA-232E output levels under specified load conditions. It requires four external 0.1µF capacitors to generate the necessary internal voltage rails. The component functions within a supply voltage range of 4.5V to 5.5V, drawing a typical operating current of 20mA. It is housed in a 24-pin SOIC package and supports an industrial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates the need for bipolar ±12V supplies, enabling single +5V or 9V to +12V operation.
• Drivers maintain ±5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps.
• Four drivers and four receivers provide full duplex communication channels.
• TTL/CMOS compatible inputs simplify interface connections to microcontrollers.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low power consumption
• Handheld devices with limited board space
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'WG+' against official documentation to confirm the package type and RoHS compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the ordering information matches the exact part number required for your design specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when four independent RS-232 channels are required in a single package. It is suitable for designs constrained by board space due to the compact SOIC footprint. Verify that the application environment stays within the 0°C to +70°C operating temperature range for optimal performance.

Drivers, Receivers, Transceivers Part Context

The MAX208CWG+ belongs to the MAX200-MAX209 series of +5V RS-232 transceivers. This family shares common architecture, including integrated charge pumps and similar pinout structures across different channel counts. The MAX208 specifically provides four driver/receiver pairs, distinguishing it from lower-channel variants like the MAX202.

Drivers, Receivers, Transceivers Replacement Considerations

MAX208CDB (Texas Instruments) offers equivalent functionality with added ±15kV ESD protection. MAX208IDWR (Texas Instruments) provides a wider operating temperature range (-40°C to +85°C). Verify pin compatibility and electrical characteristics before substitution.
