MAX202EEUE

Drivers, Receivers, Transceivers Overview

The MAX202EEUE+ is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates two drivers and two receivers within a 16-pin TSSOP package. The device operates on a single +4.5V to +5.5V supply, utilizing an internal charge pump to generate the required ±10V levels for RS-232 signaling without external bipolar supplies. It supports data rates up to 120kbps with a typical propagation delay of 10µs. The component features high electrostatic discharge protection rated at ±15kV (Human Body Model) and operates 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 Human Body Model ESD protection ensures robust performance in harsh environments or frequent connection scenarios.
• Receiver inputs feature guaranteed tight thresholds and hysteresis, allowing compatibility with TTL/CMOS logic levels alongside standard RS-232 signals.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power interface solutions
• Hand-held diagnostic tools and portable instrumentation
• Portable computers and devices with frequent serial port connections

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'UE' corresponds to the 16-pin TSSOP package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation. Ensure ordering details match the exact pinout and electrical specifications required for the target design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a full-duplex RS-232 interface is needed in a compact surface-mount form factor. It is suitable for designs constrained by board space that cannot accommodate larger DIP packages. Verify that the 120kbps data rate meets system requirements and that the TSSOP footprint aligns with PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E-MAX213E family of RS-232 transceivers. The 'E' designation indicates enhanced ESD protection compared to standard versions. The MAX202 variant specifically provides two drivers and two receivers, distinguishing it from higher-channel parts like the MAX232E or MAX241E within the same series.

Drivers, Receivers, Transceivers FAQ

Does the MAX202EEUE+ include shutdown control pins?

No, the MAX202E does not have Enable (EN) or Shutdown (SHDN) control pins. Only the MAX205E, MAX206E, MAX211E, MAX213E, and MAX241E variants include these features.

What external components are required for operation?

Four external capacitors (C1–C4) are required to support the internal charge pump. For the MAX202E, these must be 0.1µF capacitors.

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

The receiver inputs have guaranteed thresholds of 0.8V (low) and 2.4V (high), which are tighter than the ±3V required by EIA/TIA-232E. This allows direct interfacing with TTL/CMOS logic levels.
