MAX3228EBV+T

Overview

The MAX3228EBV+T is a fully integrated RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.5V to 5.5V and supports full-duplex communication with two drivers and two receivers. The device guarantees a data rate of 250kbps and features a receiver hysteresis of 300mV. It is housed in a compact 30-UCSP (2.55x3.06mm) surface-mount package. The component is rated for an operating temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Integrated ±15kV ESD protection on all RS-232 I/O pins per IEC 1000-4-2 standards
• Ultra-low power consumption with 1µA auto-shutdown mode
• Compatible with single Li+ cell operation down to +2.5V
• Requires only small 0.1µF external capacitors

Applications

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

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc./Maxim Integrated when sourcing this component. Confirm the specific suffix '+T' indicates tape-and-reel packaging. Ensure the part number matches the exact UCSP footprint dimensions of 2.55x3.06mm for PCB layout compatibility. Check for RoHS3 compliance documentation if required by regional regulations.

Selection Notes

Select this transceiver for applications requiring minimal board space due to its chip-scale package. It is suitable for battery-powered devices given the low supply current and auto-shutdown feature. Verify that the 250kbps data rate meets system requirements. Ensure the 300mV receiver hysteresis is sufficient for the noise environment of the target application.

Part Context

This component belongs to the MAX3228E family of RS-232 transceivers designed for portable electronics. It shares functional similarities with other Maxim Integrated low-voltage serial interface ICs but is distinguished by its ultra-small UCSP footprint. The family targets markets where size and power efficiency are critical constraints.
