MAX220CSE+T

Overview

The MAX220CSE+T is a +5V-powered, multichannel RS-232 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 116kbps. The device features an integrated charge pump that generates ±10V internal voltages from the single +5V supply, eliminating the need for external bipolar power sources. It provides two drivers and two receivers in a 16-pin Narrow SOIC package. Electrical specifications include a typical transmitter propagation delay of 3.5µs and a receiver propagation delay of 1µs.

Feature Summary

• Integrated charge pump circuitry eliminates the requirement for external bipolar ±12V power supplies.
• Enables single-supply operation using only a +5V source.
• Includes shutdown mode functionality to reduce overall power consumption.

Applications

• Interface translation between TTL/CMOS logic and RS-232 standards
• Multidrop RS-232 network communications
• Portable diagnostic equipment requiring low-power serial interfaces

Procurement Notes

Verify the component against official manufacturer documentation to confirm pinout compatibility and electrical ratings. Ensure the specific ordering suffix matches the required temperature grade and packaging format. Cross-reference the datasheet revision date with your design requirements to validate performance parameters.

Selection Notes

Select this component when board space is limited and external capacitors are undesirable or when operating strictly from a +5V rail. Verify that the maximum data rate of 116kbps meets system timing requirements. Confirm that the 16-pin Narrow SOIC package dimensions fit the available PCB layout constraints.

Part Context

This part belongs to the MAX220–MAX249 family of line drivers/receivers designed for EIA/TIA-232E and V.28/V.24 communication interfaces. The family offers various channel configurations and control options across multiple package types to accommodate different interface density and power management needs.
