MAX202EPE+

Drivers, Receivers, Transceivers Overview

The MAX202EPE+ is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply using an integrated charge pump to generate ±10V internal voltages, eliminating the need for external bipolar supplies. The device features two drivers and two receivers with data rates up to 120kbps. It utilizes a 16-pin Plastic DIP package and supports an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single-supply operation without requiring external bipolar voltage sources.
• Drivers maintain specified EIA/TIA-232E output signal levels under standard loading conditions.
• Receiver inputs provide tight logic thresholds to improve noise margins and ensure compatibility with TTL/CMOS logic levels.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low power consumption
• Handheld devices with limited board space
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PE' corresponds to the 16-pin Plastic DIP package and industrial temperature grade (-40°C to +85°C) as defined in the official selector guide. Confirm that the component requires four external 0.1µF capacitors for the charge pump circuit, distinguishing it from zero-component variants within the same family.

Drivers, Receivers, Transceivers Selection Notes

Select this part when a full-duplex interface with two independent channels is required alongside robust ESD protection and single-supply convenience. Ensure the application design accommodates the necessary external decoupling capacitors for the internal voltage converters. Verify that the 120kbps maximum data rate meets the system's communication speed requirements.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX200–MAX209/MAX211/MAX213 family of +5V RS-232 transceivers. The MAX202 variant specifically provides two drivers and two receivers, offering a balanced solution for bidirectional serial communication interfaces in compact electronic designs.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include MAX202ESE and MAX202EWE for surface mount alternatives. Other family members like MAX203 or MAX205 offer zero-external-capacitor configurations but differ in pinout and capacitor integration.
