MAX13223EEUP+T

Drivers, Receivers, Transceivers Overview

The MAX13223EEUP+T is a +3.0V to +5.5V-powered EIA/TIA-232 and V.28 communications interface with ±70V fault protection on the RS-232 line interface. It features two receivers and two drivers, achieving data rates up to 250kbps while maintaining true RS-232 output levels. The device utilizes Maxim’s AutoShutdown™ feature to reduce supply current to 1μA when the cable is disconnected or receivers are inactive. It operates from a single supply voltage and includes overvoltage current limiting, thermal shutdown protection, and ±8kV ESD protection. The component is specified for operation between -40°C and +85°C in a 20-pin TSSOP package.

Drivers, Receivers, Transceivers Feature Summary

• ±70V fault protection withstands load dumps, miswiring, and connector failures without damage
• AutoShutdown™ automatically enters low-power mode upon cable disconnection or receiver inactivity
• Proprietary dual charge-pump power supply delivers true RS-232 performance from a single +3.0V to +5.5V supply
• Robust protection against overvoltage, short circuits, and electrostatic discharge

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm lead-free/RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the exact temperature range and package dimensions required for your design implementation.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver for applications requiring robust fault protection against ±70V line faults. Consider the AutoShutdown feature for systems needing minimal standby power consumption. Verify that the 250kbps maximum data rate meets the communication speed requirements of the target application.

Drivers, Receivers, Transceivers Part Context

The MAX13223E belongs to the MAX1322x series of RS-232 transceivers designed for high reliability in harsh environments. It shares the same core architecture as other E-series devices but offers enhanced fault tolerance. The EEUP+ variant specifically denotes the extended temperature range and lead-free TSSOP-20 package configuration.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-to-pin replacements within the same family include the MAX13221E and MAX13225E. Verify compatibility regarding data rates and specific fault protection thresholds before substitution.

Drivers, Receivers, Transceivers FAQ

How does the AutoShutdown feature function?

The AutoShutdown feature automatically places the device into a low-power shutdown mode (1μA typical) when no valid signal levels are detected at the receiver inputs for more than 30μs. The device reactivates when a valid transition is sensed.

What is the maximum data rate supported by the MAX13223E?

The device is guaranteed to operate at data rates up to 250kbps while maintaining true RS-232 output levels under worst-case load conditions.

Can the MAX13223E survive direct shorts to power supplies?

Yes, the device is designed to survive faults such as direct shorts to power supplies, miswiring, and connector failures involving voltages in the ±70V range without damage.
