MAX209CWG+

Drivers, Receivers, Transceivers Overview

The MAX209CWG+ is a +5V RS-232 transceiver from the Analog Devices/MAXIM family, featuring integrated charge pump circuitry for single-supply operation. It provides two drivers and five receivers with TTL/CMOS compatible inputs. The device operates on a +5V supply (±10%) and requires an external V+ supply in the +9.0V to +13.2V range. It utilizes four 0.1µF external capacitors for voltage conversion. Key electrical parameters include a typical output-voltage swing of ±8V, a maximum data rate of 120kbps, and a shutdown supply current of 15µA. The component is housed in a 24-pin DIP package and supports an operating 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 exceeding 120kbps under specified load conditions.
• Includes low-power shutdown mode to reduce supply current for extended battery life in portable applications.

• Battery-powered equipment
• Handheld equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'CWG+' against official manufacturer documentation to confirm package type, temperature grade, and lead-free status. Ensure compatibility with the required +9.0V to +13.2V V+ supply rail. Confirm that the 24-pin DIP package aligns with the target PCB footprint and assembly process requirements before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-driver, five-receiver RS-232 interface is required with single-supply flexibility. It is suitable for designs needing a V+ supply between +9.0V and +13.2V rather than a full internal voltage doubler. Consider the 24-pin DIP package size and the requirement for four external 0.1µF capacitors during layout planning.

Drivers, Receivers, Transceivers Part Context

The MAX209 is part of the broader MAX200-MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. This family shares common features such as integrated charge pumps and low-power shutdown modes. The MAX209 specifically differs by requiring an external V+ supply range of +9.0V to +13.2V, distinguishing it from models like the MAX200 which generate higher voltages internally.
