MAX3227EEAE/V+

Overview

The MAX3227EEAE/V+ is a single-driver, single-receiver RS-232 transceiver manufactured by Analog Devices/Maxim Integrated. It operates on a +3.0V to +5.5V supply and supports full-duplex communication at data rates up to 1Mbps. The device features AutoShutdown Plus technology, reducing supply current to 1μA when idle. It includes ±15kV ESD protection on I/O pins and provides a READY output signal. The component is housed in a 16-pin SSOP package and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• AutoShutdown Plus functionality automatically reduces power consumption during periods of inactivity or cable disconnection.
• Integrated dual charge pump generates internal voltage rails from a single low-voltage supply using minimal external capacitors.
• Enhanced electrostatic discharge protection ensures robustness against high-voltage static events on all interface lines.

Applications

• Notebook, subnotebook, and palmtop computers
• Cellular phones and battery-powered equipment
• Automotive systems

Procurement Notes

Verify the specific suffix 'V+' indicates automotive qualification status as per official documentation. Confirm the package type matches the required footprint, as this part number corresponds to the SSOP-16 variant. Ensure compatibility with system voltage levels before procurement.

Selection Notes

Select this component for applications requiring high-speed 1Mbps RS-232 communication within space-constrained designs. It is suitable for battery-operated devices due to its ultra-low shutdown current. Verify that the thermal characteristics of the SSOP-16 package meet the system's dissipation requirements.

Part Context

This part belongs to the MAX3224E–MAX3227E family of true RS-232 transceivers. Unlike lower-speed variants in the same series, the MAX3227E specifically guarantees 1Mbps operation. It shares core features like AutoShutdown Plus and ESD protection with siblings such as the MAX3225E but differs in driver/receiver count and speed capabilities.

Replacement Considerations

The MAX3227EEUE+ serves as a pin-compatible alternative utilizing a TSSOP-16 package instead of SSOP-16. Other family members like the MAX3225E offer similar functionality but may differ in guaranteed data rates or driver counts.
