MAX208CWG+T

Drivers, Receivers, Transceivers Overview

The MAX208CWG+T is a +5V-powered, multichannel RS-232 transceiver from the Analog Devices/MAXIM family. It features four drivers and four receivers with full-duplex communication capability. The device operates within a supply voltage range of 4.75V to 5.25V and supports data rates up to 120kbps. It utilizes an integrated charge pump to generate internal ±10V rails from a single +5V source, requiring only four external 0.1µF capacitors. The component is housed in a 24-pin SOIC package and functions reliably across a temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for bipolar ±12V supplies, enabling operation from a single +5V source.
• Drivers maintain standard EIA/TIA-232E output signal levels at data rates exceeding 120kbps under specified load conditions.
• Receivers convert RS-232 signals to CMOS logic levels with tight input thresholds that improve noise margins.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'WG' corresponds to the SOIC-24 package and lead-free status when sourcing. Confirm the operating temperature grade matches the application requirements, as other variants exist. Ensure the datasheet revision aligns with the manufacturing date code for accurate electrical specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this part when four independent transmit and receive channels are required on a single IC. It is suitable for designs constrained by space due to the compact SOIC-24 footprint. Consider alternatives if higher data rates or additional control pins like shutdown are necessary for the specific system architecture.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX200-MAX209 series of RS-232 transceivers. These parts share a common architecture featuring integrated charge pumps and minimal external component counts. The MAX208 specifically provides a balanced configuration of four drivers and four receivers within the family.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include the MAX208EAG-T for extended temperature ranges. Other family members like the MAX202 or MAX206 offer different driver/receiver counts but may require schematic adjustments.
