MAX212EAG

Drivers, Receivers, Transceivers Overview

The MAX212EAG is a low-power RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates driver, receiver, and charge pump circuits to enable full RS-232 communication using only external 0.1µF capacitors. The device operates from a single +5V power supply and features ESD protection exceeding ±15kV on all pins. It supports data rates up to 120kbps and includes flow control signals for modem applications. The component is housed in a 24-pin SSOP package with an industrial temperature range.

• Integrated charge pump eliminates the need for dual voltage supplies
• Single +5V operation reduces system complexity and cost
• Robust electrostatic discharge protection on all signal lines
• Supports standard RS-232 protocol with minimal external components

Drivers, Receivers, Transceivers Applications

• Industrial serial communication interfaces
• Modem equipment and telecommunications hardware
• Portable battery-powered devices requiring RS-232 connectivity
• Data acquisition systems with serial data logging

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EAG' against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 24-SSOP configuration. Check for RoHS compliance status if required by regional regulations. Confirm availability through authorized distributors as lead times may vary based on production cycles.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring reliable RS-232 communication with minimal external capacitance. It is suitable for applications where space constraints limit the use of larger capacitors typically required for older transceivers. Consider the operating temperature range and ESD requirements to ensure suitability for the target environment. Verify that the single-supply architecture aligns with the system's power budget.

Drivers, Receivers, Transceivers Part Context

The MAX212 belongs to Maxim's family of low-power RS-232 transceivers designed for portable and battery-operated applications. It simplifies design by integrating the charge pump, reducing the bill of materials compared to earlier generations. This series is widely used in industrial and consumer electronics where robust serial communication is essential. The EAG variant specifically denotes the package and thermal characteristics within this product line.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other MAX212 variants with different suffixes indicating package or temperature changes. Cross-reference with MAX3232 or MAX3243 if higher data rates or additional drivers are needed. Ensure pin compatibility and electrical specifications match before substitution. Consult official datasheets for any functional differences between legacy and newer revisions.
