MAX223EWI

Drivers, Receivers, Transceivers Overview

The MAX223EWI+T is a +5V-powered, multichannel RS-232 transceiver featuring four drivers and five receivers. It operates within a supply voltage range of 4.5V to 5.5V at a typical current of 15mA. The device supports data rates up to 120kb/s with a propagation delay of 40µs. It includes an integrated shutdown mode consuming 50µA maximum. Available in a 28-pin Wide SOIC package, it functions across industrial temperatures from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the need for external bipolar ±12V supplies.
• Single +5V supply operation reduces system power requirements.
• Shutdown mode significantly lowers power consumption for battery applications.

Drivers, Receivers, Transceivers FAQ

Does the MAX223EWI+T require external capacitors?

Yes, the datasheet specifies the use of external capacitors (typically 1.0µF) for the internal charge pump circuits to generate the necessary ±10V levels.

What is the input voltage tolerance on receiver pins?

The receivers can tolerate input voltages up to ±30V, protecting the internal circuitry from high-voltage faults on the RS-232 lines.
