MAX209CNG+

Drivers, Receivers, Transceivers Overview

The MAX209CNG+ is a +5V-powered, multichannel RS-232 transceiver from the MAX200–MAX209 family. It features two drivers and three receivers with integrated charge pump circuitry for single-supply operation. The device operates on a VCC supply of +5V ±10% and accepts an external V+ supply ranging from +9.0V to +13.2V. It supports data rates exceeding 120kbps while maintaining ±5V output signal levels compliant with EIA/TIA-232E specifications. The component is housed in a 24-pin Narrow Plastic DIP package and functions within an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single +5V supply operation without requiring bipolar ±12V power rails.
• Includes two dedicated drivers and three receivers for multichannel serial communication.
• Supports low-power shutdown mode to minimize current consumption during idle periods.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm that the required V+ supply voltage falls within the specified +9.0V to +13.2V range for proper functionality. Ensure compatibility with existing PCB footprints for the 24-pin narrow DIP configuration before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a design requires two transmit channels and three receive channels powered by a single +5V logic rail. It is suitable for applications where space savings from integrated charge pumps are prioritized over the zero-component solutions offered by other family members. Verify that the external V+ supply capability matches the system's available voltage levels.

Drivers, Receivers, Transceivers Part Context

The MAX209CNG+ belongs to the MAX200–MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. This series is designed to replace traditional dual-supply interfaces by integrating voltage conversion directly onto the chip. The 'C' designation indicates commercial temperature performance, while the 'N' prefix typically denotes the narrow plastic DIP package variant.
