MAX220EPE+

Drivers, Receivers, Transceivers Overview

The MAX220EPE+ is a +5V-powered, multichannel RS-232 line driver and receiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 200kbps. The device features an integrated charge pump that generates internal ±10V rails from a single +5V source, eliminating the need for external bipolar supplies. It provides two drivers and two receivers in a 16-pin PDIP package with an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the requirement for external bipolar power supplies.
• Enables single-supply operation using only a +5V input.
• Includes a low-power shutdown mode to reduce overall system energy consumption.

Drivers, Receivers, Transceivers Applications

• Interface translation between TTL/CMOS logic levels and RS-232 standards
• Multidrop RS-232 communication networks
• Portable diagnostic equipment requiring compact interface solutions

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EPE+' against the manufacturer's current ordering guide to confirm the PDIP-16 package and industrial temperature rating (-40°C to +85°C). Ensure the component meets RoHS compliance requirements if mandated by your project specifications. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require RS-232 communication but lack access to negative voltage rails. The integrated charge pump simplifies the bill of materials by removing the need for external voltage inverters. Verify that the required data rate does not exceed 200kbps and that the physical footprint accommodates the 16-pin DIP package.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX220–MAX249 family of +5V-powered RS-232 transceivers. While other members of this series offer varying channel counts or integrated capacitors, the MAX220 specifically requires external capacitors for its charge pump operation. This family is designed to replace traditional RS-232 transceivers that rely on dual positive and negative power supplies.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional replacements within the same family include the MAX232EPE+, which utilizes smaller external capacitors. For applications requiring fewer channels, the MAX221EPE+ serves as a single-channel alternative. Ensure any substitute maintains the same PDIP-16 package and extended temperature range specifications.
