MAX13223EEUP+

Drivers, Receivers, Transceivers Overview

The MAX13223EEUP+ is a +3.0V to +5.5V-powered EIA/TIA-232 and V.28 communications interface featuring ±70V fault protection on the RS-232 line interface. It incorporates Maxim’s AutoShutdown™ feature, achieving a typical supply current of 1μA when inactive or disconnected. The device contains two receivers and two drivers, guaranteed for data rates up to 250kbps. It operates from a single supply voltage using a proprietary dual charge-pump power supply and low-dropout transmitter. The component is available in a 20-pin TSSOP package and is specified over an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Robust protection against load dumps, miswiring, and connector failures with ±70V fault tolerance
• AutoShutdown functionality automatically reduces supply current to 1μA during inactivity or cable disconnection
• True RS-232 performance maintained at data rates up to 250kbps even from a +3.0V supply voltage

• Telematics Equipment
• Base Stations
• Utility Meters
• Industrial Equipment
• Telecomm Equipment
• POS Terminal Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm lead-free and RoHS compliance status. Confirm the package type matches the required 20-pin TSSOP footprint. Ensure the temperature grade corresponds to the industrial range of -40°C to +85°C. Cross-reference the manufacturer part number directly with official Analog Devices documentation to validate authenticity and revision history before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver for applications requiring high-voltage fault tolerance on RS-232 lines. The device is suitable for designs needing low-power consumption through automatic shutdown features. Verify that the system operates within the +3.0V to +5.5V supply voltage range. Ensure external capacitor values align with the specific supply voltage requirements for optimal charge pump performance.

Drivers, Receivers, Transceivers Part Context

The MAX13223E belongs to the Maxim Integrated RS-232 transceiver family designed for robust communication interfaces. It shares functional similarities with other devices in the series but is distinguished by its specific ±70V fault protection capabilities and AutoShutdown technology. The EEUP+ designation indicates the specific pin-package configuration and environmental compliance status within the product lineup.
