MAX3318EUP

Overview

The MAX3318EUP is a low-power, RS-232-compatible transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates on a single 2.5V supply voltage with a maximum rating of 3V and draws only 1mA of operating current. The device features two drivers and two receivers, supporting data rates up to 460kbps with a propagation delay of 0.175µs. It includes a shutdown mode for power conservation and provides 15kV ESD protection on I/O pins. The component is housed in a TSSOP-20 package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated dual driver and dual receiver architecture for full-duplex communication
• Ultra-low power consumption with dedicated shutdown control capability
• Robust electrostatic discharge protection rated at 15kV on input and output lines

Applications

• Portable battery-powered equipment requiring low-voltage operation
• Industrial control systems utilizing RS-232 serial communication
• Handheld terminals and mobile computing devices

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence or lifecycle changes directly with Analog Devices. Ensure pinout compatibility during integration planning.

Selection Notes

Select this component when a 2.5V supply rail is available and low quiescent current is critical. Verify that the 460kbps speed meets system requirements. Compare against the MAX3318IPWR if Texas Instruments sourcing is preferred for identical electrical specifications.

Part Context

This part belongs to the MAX3318E series of RS-232 transceivers designed for portable applications. It shares functional similarities with the MAX3380E but differs in supply voltage range and driver count. The EEUP suffix typically denotes the extended temperature range and TSSOP-20 packaging variant.

Replacement Considerations

MAX3318IPWR (Texas Instruments) offers equivalent electrical performance and pinout compatibility.
