MAX3318EAP+

Overview

The MAX3318EAP+ is a low-power, RS-232-compatible transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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 TSSOP-20 package. It features ±15kV ESD protection on all pins, ensuring robust performance in harsh environments. The component includes a shutdown mode that reduces supply current to typically 1µA, making it suitable for battery-powered applications.

Feature Summary

• Integrated ±15kV ESD protection on all RS-232 signal pins
• Ultra-low power consumption with 1µA shutdown mode
• Single 2.5V supply operation capability
• Full duplex communication with integrated charge pump

Applications

• Portable computers and notebooks
• Battery-operated industrial instruments
• Handheld terminals and POS systems
• Medical equipment requiring low power interfaces

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc. or Maxim Integrated when sourcing. Confirm the suffix 'E' indicates industrial temperature range and 'AP' denotes the SSOP-20 package variant. Ensure RoHS compliance documentation matches the specific batch. Cross-reference the Mouser part number 700-MAX3318EAP for accurate identification during procurement processes.

Selection Notes

Select this component for designs requiring low voltage operation at 2.5V. It is appropriate where space constraints favor the SSOP-20 package over larger alternatives. Consider the 460kbps speed limit for high-speed requirements. Evaluate the shutdown current specification for strict battery life constraints in portable devices.

Part Context

This part belongs to the MAX3318 series of RS-232 transceivers. It shares functional similarities with the MAX3317 but offers enhanced ESD protection. The device is designed to replace older dual-supply RS-232 solutions. It fits within the broader portfolio of Maxim Integrated interface ICs focused on low-power serial communications.

Replacement Considerations

The MAX3318ECUP+ is a pin-compatible alternative in a TSSOP-20 package. Verify package dimensions between SSOP-20 and TSSOP-20 for board layout compatibility. Check if the replacement meets the same -40°C to +85°C operating temperature range.
