MAX3222EEUP/V+T

Overview

The MAX3222EEUP/V+T is a true RS-232 transceiver manufactured by Analog Devices / Maxim Integrated. It operates on a single 3.0V to 5.5V power supply and supports data rates up to 1Mbps. The device integrates two drivers and two receivers in full-duplex operation within a 20-TSSOP package. Key electrical specifications include a maximum propagation delay of 0.3µs, an operating supply current of 1mA, and ESD protection rated at 15kV. It features a shutdown mode for power reduction and complies with AEC-Q100 automotive standards.

Feature Summary

• Integrated ESD protection on all pins to withstand high-voltage electrostatic discharge events
• Low-power shutdown capability reduces supply current significantly during idle periods
• Single-supply operation compatible with standard 3V and 5V logic systems

Applications

• Automotive telematics and infotainment systems requiring robust interface protection
• Industrial equipment utilizing serial communication protocols
• Portable devices needing low-power RS-232 connectivity

Procurement Notes

Verify the specific suffix V+ against official manufacturer documentation to confirm voltage range and temperature grade alignment. Confirm RoHS compliance status through the latest datasheet revision. Check for any recent product change notices or end-of-life announcements from Analog Devices prior to finalizing procurement plans.

Selection Notes

Select this component when designing systems that require high ESD immunity alongside low standby power consumption. Ensure the application environment falls within the specified commercial temperature range if relying on the standard variant parameters. Verify that the 20-TSSOP footprint matches the PCB layout constraints and that the 1Mbps speed meets the system's baud rate requirements.

Part Context

This part belongs to the MAX3222E series of true RS-232 transceivers designed for mobile and handheld applications. The family emphasizes power efficiency and reliability in harsh environments. The EEUP/V+T designation indicates a specific tape-and-reel packaging configuration with defined thermal and electrical characteristics distinct from tube-packaged variants.
