DS229SN+

Drivers, Receivers, Transceivers Overview

The DS229SN+ is a triple RS-232 driver/receiver integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V power supply, utilizing internal dual charge pumps to generate ±10V for RS-232 signaling without external high-voltage supplies. The device features three drivers and three receivers, supporting data rates up to 200 kbps with typical operation at 116 kbps. It meets EIA-232E and V.28 specifications, requiring only 0.1 µF capacitors for the charge pump circuitry. The component is housed in a 20-pin SOIC package (7.50mm width) and supports an industrial operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Generates RS-232 voltage levels from a single +5V supply using on-board dual charge pumps
• Fully compliant with EIA-232E and V.28/V.24 standards
• Includes three TTL/CMOS compatible drivers and three protected receivers
• Operates with small 0.1 µF charge pump capacitors

Drivers, Receivers, Transceivers Applications

• Industrial automation systems requiring serial communication
• Embedded solutions needing RS-232 interface conversion
• Equipment with height restrictions utilizing surface-mount packaging

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm the industrial temperature grade (-40°C to +85°C). Ensure the procurement matches the exact package type required, as the base part number may correspond to different physical packages such as DIP or TSSOP. Confirm RoHS compliance status through official datasheets prior to integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single +5V supply is available and external high-voltage generation is undesirable. The DS229SN+ is suitable for applications requiring full duplex communication with three independent channels. Consider the 20-pin SOIC footprint constraints and verify that the 0.1 µF capacitor requirement fits within the board layout limitations.

Drivers, Receivers, Transceivers Part Context
