MAX209ENG+

Drivers, Receivers, Transceivers Overview

The MAX209ENG+ is a +5V-powered RS-232 transceiver from the MAX200-MAX209 family, manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers with integrated charge pump circuitry for single-supply operation. The device operates from a VCC supply of +5V ±10% and a V+ supply ranging from +9.0V to +13.2V. It supports data rates in excess of 120kbps while maintaining ±5V EIA/TIA-232E output levels under worst-case conditions. The component is housed in a 14-pin Plastic DIP package and is rated for an operating temperature range of -40°C to +85°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.
• Includes low-power shutdown mode to save power for battery-operated equipment.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'ENG+' against official manufacturer documentation to confirm pinout, package type, and temperature grade. Ensure compatibility with existing PCB footprints and voltage requirements before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-driver, dual-receiver RS-232 interface is required with a single +5V logic supply. It is suitable for applications needing high data rates up to 120kbps without external charge pump components.

Drivers, Receivers, Transceivers Part Context

The MAX209 is part of the broader MAX200–MAX209/MAX211/MAX213 family of +5V-powered multichannel RS-232 drivers and receivers. This family shares common architecture but varies in driver/receiver counts and package options.

Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes within the same family include the MAX201, which shares similar electrical characteristics and pin configurations for dual-channel RS-232 communication.
