MAX3229EEBV-T

Overview

The MAX3229EEBV-T is a low-power RS-232 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates from a single power supply ranging from +2.5V to +5.5V and supports data rates up to 250kbps. The device integrates charge pumps requiring only four external 0.1µF capacitors, eliminating the need for inductors or transformers. It features enhanced electrostatic discharge protection rated at ±15kV via IEC 1000-4-2 Air-Gap Discharge and ±8kV via Contact Discharge. The component is housed in a compact 6mm x 5mm UCSP package.

Feature Summary

• Integrated charge pump circuitry utilizing small 0.1µF capacitors for voltage generation
• High-level ESD protection on all RS-232 I/O pins ensuring robust signal integrity
• AutoShutdown mode providing ultra-low standby current consumption
• Single-supply operation compatible with Li+ cell power sources

Applications

• Personal Digital Assistants (PDAs)
• Cellular phones and handheld devices
• Data lump cables
• Set-top boxes

Procurement Notes

Verify the specific suffix 'EBV' against official manufacturer documentation to confirm package type and temperature range specifications. Confirm end-of-life status and availability through authorized distributors, as this component may be subject to discontinuation or limited stock constraints.

Selection Notes

Select this component when designing space-constrained systems requiring RS-232 connectivity with minimal external passive components. Ensure the application environment meets the specified ESD protection requirements and that the operating voltage aligns with the single-supply range of 2.5V to 5.5V.

Part Context
