MAX3228EEBV-T

Overview

The MAX3228EEBV-T is a low-power RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single power supply ranging from +2.5V to +5.5V and supports data rates up to 250kbps. The device integrates two drivers and two receivers, featuring ±15kV ESD protection on I/O pins per IEC 1000-4-2 standards. It utilizes small 0.1µF external capacitors and includes a 1µA auto-shutdown mode. The component is housed in a compact 6x5mm UCSP package.

Feature Summary

• Integrated ±15kV ESD protection for enhanced signal line durability
• Ultra-low power consumption with 1µA auto-shutdown capability
• Compact chip-scale packaging for space-constrained designs
• Single-supply operation compatible with Li+ cell voltage ranges

Applications

• Personal Digital Assistants
• Cell Phones and Handheld Devices
• Data Lump Cables
• Set-Top Boxes

Procurement Notes

Verify the obsolete status of this specific part number before design finalization. Confirm that the UCSP package dimensions align with current PCB footprint requirements. Ensure that the 250kbps data rate meets system timing constraints. Check for available replacement components if long-term supply stability is required for production.

Selection Notes

Select this component when designing portable devices requiring minimal board space and low standby current. The wide input voltage range allows direct connection to single-cell lithium batteries. Verify that the receiver lag and driver output levels satisfy the specific RS-232 interface requirements of the target application.

Part Context

This device belongs to the MAX3228E family of RS-232 transceivers designed for mobile and handheld applications. It shares functional similarities with other Maxim low-power serial interface chips but distinguishes itself through its ultra-small UCSP footprint and robust ESD protection characteristics suitable for consumer electronics.
