MAX202EEWE+T

Drivers, Receivers, Transceivers Overview

The MAX202EEWE+T is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +4.5V to +5.5V supply and includes an integrated charge pump to generate the required ±10V logic levels, eliminating the need for external bipolar supplies. The device features two drivers and two receivers with a maximum data rate of 120kbps. It provides high electrostatic discharge protection rated at ±15kV (Human Body Model). The component is housed in a 16-pin Wide SOIC package and supports an industrial operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single-supply operation without requiring external bipolar voltage rails.
• High robustness against electrostatic discharge with ±15kV Human Body Model protection on all RS-232 I/O pins.
• Receiver inputs feature guaranteed hysteresis to ensure clean output transitions despite slow signal rise/fall times or noise.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low power consumption
• Hand-held diagnostic tools
• Portable instrumentation systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the 'E' designation corresponds to the extended temperature grade (-40°C to +85°C) rather than the commercial grade. Ensure the wide SOIC footprint matches the PCB layout requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require RS-232 communication under harsh environmental conditions due to its enhanced ESD tolerance. It is suitable for applications where space constraints prohibit dual-voltage power supplies. Verify that the 120kbps data rate meets the system's throughput requirements and that the 16-pin wide SOIC package is compatible with the assembly process.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E-MAX213E family of RS-232 transceivers designed for single-supply applications. The 'E' suffix denotes the extended temperature variant, while the 'W' indicates the wide SOIC package style. The '+T' suffix specifies the reel packaging format for automated surface-mount assembly.

Drivers, Receivers, Transceivers FAQ

Does the MAX202EEWE+T include internal shutdown control?

No, the MAX202E does not have built-in shutdown or enable control pins; these features are available in other family members like the MAX205E or MAX211E.

What external components are required for operation?

Four external capacitors (typically 0.1µF) are required to support the internal charge pump voltage conversion circuitry.

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

The receiver inputs have tighter thresholds (0.8V low, 2.4V high) than the standard ±3V requirement, allowing compatibility with TTL/CMOS logic levels.
