MAX3229EBV

Overview

The MAX3229EBV is a low-power RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features three drivers and three receivers, supporting full-duplex communication with a data rate of 125 kbps. The device operates on a single 3 V to 5.5 V supply and includes integrated charge pumps for RS-232 voltage generation. It is housed in a compact 16-TSSOP package (4.4mm width) and is rated for an operating temperature range of -40°C to +85°C. The receiver provides 30-kV ESD protection per IEC 61000-4-2 standards.

Feature Summary

• Integrated charge pump eliminates the need for external capacitors
• Low quiescent current design extends battery life
• High ESD protection ensures robust signal integrity

Applications

• Portable medical equipment
• Handheld terminals
• Battery-powered instrumentation

Procurement Notes

Verify the specific suffix 'EBV' against official manufacturer documentation to confirm the exact tape-and-reel packaging configuration and temperature grade. Confirm RoHS compliance status through the latest datasheet revision or environmental information sheet provided by Analog Devices.

Selection Notes

Select this component when designing space-constrained systems requiring RS-232 connectivity with minimal external components. Ensure the application environment stays within the specified -40°C to +85°C range. Verify that the 125 kbps data rate meets the system's throughput requirements compared to higher-speed alternatives.

Part Context

This part belongs to the MAX322x family of RS-232 transceivers designed for low-power applications. It shares functional similarities with other members like the MAX3232 but offers optimized power consumption and specific pin configurations suitable for portable devices. The EBV suffix typically denotes a specific reel quantity and packaging variant within the TSSOP-16 form factor.

Replacement Considerations

Direct replacements include the MAX3232EIB+ or MAX3232EBI+ from the same manufacturer family. Verify pin compatibility and electrical specifications before substitution. Other manufacturers offer similar low-power RS-232 transceivers, but pin-to-pin compatibility must be confirmed via cross-reference tools.
