DS229SN

Drivers, Receivers, Transceivers Overview

The DS229SN is a triple RS-232 driver/receiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-SOIC package. It operates from a single +5V supply (4.5V to 5.5V) using internal charge pumps to generate ±10V levels. The device features three drivers and three receivers compliant with EIA-232E and V.28 standards. Data rates are guaranteed up to 116 kbits/sec, with typical slew rates of 20 V/µs unloaded. It requires only 0.1 µF external capacitors for the charge pump circuitry.

Drivers, Receivers, Transceivers Feature Summary

• Generates RS-232 voltage levels from a single +5V power supply via on-board dual charge pumps
• Fully compliant with EIA-232E and V.28/V.24 communication standards
• Includes internal pullup resistors allowing unused transmitter inputs to remain unconnected
• Provides receiver hysteresis to improve noise immunity

Drivers, Receivers, Transceivers Applications

• Industrial control systems requiring RS-232 connectivity
• Embedded solutions needing compact serial communication interfaces
• Applications with height restrictions utilizing surface mount packaging

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific 'N' suffix indicates the industrial temperature range variant (-40°C to +85°C). Check current availability status as this component may be discontinued or subject to limited supply constraints depending on the distribution channel.

Drivers, Receivers, Transceivers Selection Notes

Select the DS229SN when an industrial temperature range is required for SOIC applications. Ensure the design accommodates the necessary 0.1 µF charge pump capacitors. Verify that the system logic levels are compatible with the TTL/CMOS inputs and outputs. Consider the data rate requirements against the guaranteed 116 kbits/sec limit under worst-case conditions.

Drivers, Receivers, Transceivers Part Context

The DS229SN belongs to the DS229 family of triple RS-232 transceivers. It is functionally compatible with the DS1229. The 'SN' designation specifically identifies the 20-pin Small Outline Integrated Circuit (SOIC) package version configured for the extended industrial operating temperature range, distinguishing it from commercial variants.

Drivers, Receivers, Transceivers Replacement Considerations

The DS1229 is documented as functionally compatible with the DS229 series. Verify pinout compatibility and electrical specifications before substitution.
