MAX3248EEAI

Overview

The MAX3248EEAI+ is a low-power RS-232 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of +3.0V to +5.5V and supports data rates up to 250kbps. The device features one driver and three receivers, providing full-duplex communication capabilities. It incorporates 15kV ESD protection on both I/O and logic pins. The typical operating supply current is 2mA, with a shutdown current of 10nA. It functions reliably across an extended temperature range from -40°C to +85°C and is housed in a 28-pin SSOP package.

Feature Summary

• Integrated 15kV electrostatic discharge protection for robust signal integrity
• Ultra-low power consumption with 10nA shutdown mode for battery efficiency
• Single-driver and triple-receiver configuration for versatile interface needs

Applications

• Portable equipment requiring low-voltage operation
• Industrial control systems with harsh electrical environments
• Communication devices utilizing RS-232 protocols

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and functional compatibility. Ensure the component meets RoHS requirements if mandated by project specifications. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when a single transmitter and multiple receivers are required within a low-power constraint. Compare against similar models like the MAX3238 or MAX3243 if different driver/receiver counts are needed. Verify that the 250kbps speed limit aligns with system timing requirements and that the SSOP package fits the PCB layout constraints.

Part Context

This part belongs to the Maxim Integrated MAX32xx series of RS-232 transceivers designed for low-voltage applications. It shares architectural similarities with other members of the family but differs in channel configuration. The EEAI suffix indicates a specific temperature range and package type within the broader product line.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MAX3248E without the plus sign if lead-free compliance is not strictly enforced. Evaluate the MAX3238EEAI+ if five drivers are required instead of one. Confirm electrical parameter equivalence before substituting.
