MAX3318EAP

Overview

The MAX3318EAP is a low-power, RS-232-compatible transceiver manufactured by Analog Devices Inc. (formerly Maxim Integrated). It operates from a single 2.5V supply and supports data rates up to 460kbps. The device integrates two drivers and two receivers in a full-duplex configuration. It features ±15kV ESD protection on all pins per IEC 61000-4-2 standards. The unit includes a shutdown mode that reduces supply current to typically 1µA. It is housed in a 20-pin SSOP package and is rated for operation over an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated ±15kV ESD protection on all RS-232 signal pins compliant with IEC 61000-4-2 standards
• Ultra-low power consumption with active supply current of 2mA and shutdown mode reducing current to 1µA
• Single 2.5V supply operation eliminating the need for external charge pumps or negative voltage supplies

Applications

• Portable battery-powered equipment requiring low-voltage RS-232 communication
• Industrial control systems operating in environments with high electrostatic discharge risk
• Medical devices necessitating robust interface protection and low power draw

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Ensure the component source is authorized to guarantee authenticity. Check for RoHS compliance status relevant to your region's regulations before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits powered by a single 2.5V rail. It is suitable for applications requiring high ESD immunity without external protection components. Compare performance against the MAX3317 series if different packaging or ESD ratings are required for the target enclosure design.

Part Context

This part belongs to the MAX3318 family of low-power RS-232 transceivers. It shares functional similarities with the MAX3317 but differs in packaging and specific ESD protection levels. The device is part of Analog Devices' portfolio following the acquisition of Maxim Integrated, maintaining legacy part numbering conventions.

Replacement Considerations

The MAX3318EAP+ is a lead-free variant of the same functional device. Verify pin compatibility with the MAX3317EEAP if alternative sourcing is necessary, noting differences in ESD protection specifications.
