DS229

Drivers, Receivers, Transceivers Overview

The DS229 is a triple RS-232 driver/receiver pair that generates RS-232 voltage levels from a single +5-volt power supply. It contains three drivers and three receivers, with data rates guaranteed up to 116 kbits/sec. The device uses on-board charge pumps to convert the +5V supply to ±10 volts, eliminating the need for additional supplies. It operates within a 4.5V to 5.5V range and meets EIA-232E and V.28 specifications. Available in 20-pin DIP, SOIC, and TSSOP packages.

Drivers, Receivers, Transceivers Feature Summary

• Generates RS-232 voltage levels from a single +5V supply using internal dual charge pump converters
• Fully compliant with EIA-232E and V.28/V.24 standards
• Operates with small external capacitors of 0.1 µF minimum
• Includes optional industrial temperature range availability

Drivers, Receivers, Transceivers Applications

• Serial communication interfaces requiring RS-232 compliance
• Applications restricted to single +5V power sources
• Systems needing compact solutions with minimal external components

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant required, such as standard or industrial temperature range versions (e.g., DS229N). Confirm lead times and availability status directly with authorized distributors, as this component may be subject to discontinuation or limited stock conditions depending on current market supply chains.

Drivers, Receivers, Transceivers Selection Notes

Select the appropriate package type based on mechanical constraints: 20-pin DIP for through-hole, SOIC for surface mount, or TSSOP for height-restricted applications. Ensure the design accommodates the necessary external 0.1 µF charge pump capacitors. Verify that the operating environment falls within the specified commercial or industrial temperature ranges if applicable.

Drivers, Receivers, Transceivers Part Context

The DS229 belongs to the Maxim Integrated line of interface ICs designed for serial communications. It serves as a cost-effective solution for converting TTL/CMOS logic levels to RS-232 voltages without requiring complex external power generation circuits. Its integration simplifies board layout by reducing the number of required passive components.

Drivers, Receivers, Transceivers Replacement Considerations

The DS1229 is noted as compatible with the DS229. When substituting, verify pinout compatibility and ensure the replacement part supports the required data rate and voltage swing specifications for the specific application load.
