MAX202EESE-T

Drivers, Receivers, Transceivers Overview

The MAX202EESE-T is a dual driver and dual receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V power supply, utilizing an internal charge pump to generate the necessary voltages for EIA/TIA-232E compliance without requiring external bipolar supplies. The device supports data rates up to 120 kb/s with full duplex communication capabilities. Key electrical specifications include a supply voltage range of 4.5V to 5.5V, a typical operating supply current of 15 mA, and propagation delay of 10 µs. It features ±15 kV electrostatic discharge (ESD) protection on both drivers and receivers. The component is housed in a 16-pin SO-Narrow package and is rated for operation within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuit enables operation from a single +5V power source, eliminating the need for external negative voltage supplies.
• Robust ±15 kV electrostatic discharge (ESD) protection on all inputs and outputs prevents latch-up and damage during high-voltage events.
• Full duplex communication architecture provides independent drivers and receivers for simultaneous bidirectional data transfer.
• Compliance with EIA/TIA-232E and CCITT V.28 standards ensures reliable signal integrity at data rates up to 120 kb/s.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power serial communication interfaces
• Portable diagnostic devices and handheld instruments
• Laptops, ultrabooks, and tablet computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the ordering part number matches the exact package variant required for the PCB footprint. Cross-reference the datasheet revision date to confirm technical specifications have not changed. Validate supplier authenticity to avoid counterfeit components.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring standard RS-232 levels with single-supply convenience. Consider the 120 kb/s speed limit when designing for higher baud rate requirements. Evaluate the 16-pin narrow SOIC footprint against available board space constraints. Compare power consumption metrics if battery life is a critical design parameter. Verify that the ±15 kV ESD rating meets the environmental safety requirements of the target deployment.

Drivers, Receivers, Transceivers Part Context

The MAX202E belongs to the broader MAX202E-MAX213E family of RS-232 transceivers designed for harsh environments. This series integrates charge pumps to simplify power supply design for single-voltage systems. The MAX202E specifically offers a dual-driver, dual-receiver configuration suitable for common serial port implementations. Other variants in the family may offer different pin counts, shutdown modes, or capacitor integration options.
