MAX202EPE

Drivers, Receivers, Transceivers Overview

The MAX202EPE is a dual driver and receiver RS-232 transceiver designed for single +5V supply operation. It features an integrated charge pump that generates the required ±10V internal voltages, eliminating the need for external bipolar supplies. The device supports data rates exceeding 120kbps while maintaining EIA/TIA-232E output levels under worst-case conditions. Electrical specifications include a typical VCC power-supply current of 15mA, a maximum data rate of 120kbps, and a propagation delay of 10µs. It operates within a temperature range of -40°C to +85°C and utilizes a 16-pin Plastic DIP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single +5V or 9V to +12V supply operation without requiring bipolar voltage sources.
• Drivers maintain specified ±5V EIA/TIA-232E output signal levels at data rates in excess of 120kbps.
• Receiver inputs feature guaranteed thresholds of +0.8V and +2.4V, providing improved noise margins compared to standard RS-232 requirements.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment
• Handheld equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PE' corresponds to the 16-pin Plastic DIP package and the '-E' grade indicating the -40°C to +85°C extended temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering details match the exact component designation to avoid pinout mismatches with other package variants.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring full-duplex RS-232 communication powered by a single +5V rail. It is suitable for applications where board space savings from integrated capacitors are not critical, as it requires four external 0.1µF capacitors. Consider alternatives like the MAX203 if zero external components are preferred for compact layouts.

Drivers, Receivers, Transceivers Part Context

The MAX202EPE belongs to the MAX200-MAX209 family of +5V RS-232 transceivers. This series shares common architecture including the internal charge pump and driver/receiver stages. The 'MAX202' designation specifically indicates a configuration with two drivers and two receivers, distinguishing it from single-channel or multi-channel variants within the same product line.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the MAX202CSE (Commercial grade) and MAX202EWE (Wide SOIC package). Verify pin compatibility and thermal performance when substituting between different package types such as Plastic DIP and Narrow SOIC.
