MAX202EEUE+T

Drivers, Receivers, Transceivers Overview

The MAX202EEUE+T is a single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates two drivers and two receivers within a 16-pin TSSOP package, supporting full-duplex communication at data rates up to 120kbps. The device operates on a single +4.5V to +5.5V supply voltage, utilizing an internal charge pump to generate the required ±10V levels for RS-232 signaling without external bipolar supplies. It features high electrostatic discharge protection rated at ±15kV via the Human Body Model. The typical supply current is 15mA, and it functions reliably across an extended temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single +5V supply operation, eliminating the need for external bipolar power sources.
• High ±15kV ESD protection on driver outputs and receiver inputs ensures reliability in harsh environments.
• Receiver inputs feature guaranteed tight thresholds (0.8V low, 2.4V high) compatible with TTL/CMOS logic levels.
• Internal pull-up resistors on transmitter inputs simplify interface connections for unused drivers.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power serial communication
• Hand-held diagnostic tools and portable instrumentation
• Notebook computers and mobile devices with frequent port connection changes

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix EEUE+T against official manufacturer documentation to confirm the TSSOP package and industrial temperature grade. Ensure that the required 0.1μF external capacitors are included in the bill of materials, as they are mandatory for the internal charge pump operation. Confirm RoHS compliance status through the supplier's certification documents prior to integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require robust ESD protection and single-supply operation. It is suitable for applications needing two independent RS-232 channels. Compare against the MAX232E if higher drive capability or different capacitor requirements are needed. Ensure the PCB layout accommodates the 16-TSSOP footprint and provides adequate thermal relief for the operating temperature range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E-MAX213E family of RS-232 transceivers from Maxim Integrated. The 'E' designation indicates enhanced ESD protection compared to standard versions. The 'UE' suffix specifies the 16-pin Thin Shrink Small Outline Package (TSSOP) with an extended industrial temperature range. This family shares architectural similarities with the MAX232E but differs in pinout and capacitor requirements.

Drivers, Receivers, Transceivers FAQ

Does the MAX202EEUE+T include a shutdown mode?

No, the MAX202E does not feature a shutdown control pin. Only specific members of the family, such as the MAX205E, MAX206E, MAX211E, MAX213E, and MAX241E, include shutdown functionality.

What external components are required for operation?

Four 0.1μF capacitors are required to support the internal charge pump voltage converters. These capacitors connect to the C1+, C1-, C2+, and C2- terminals.

How does the receiver input threshold compare to standard RS-232 specifications?

The receiver inputs have guaranteed thresholds of 0.8V for logic low and 2.4V for logic high. These are tighter than the standard ±3V RS-232 thresholds, allowing direct compatibility with TTL and CMOS logic levels.
