MAX3107ETG/V+

Overview

The MAX3107ETG/V+ is a single-channel UART interface integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.65 V to 3.6 V and supports data rates up to 24 Mb/s. The device features a 128-byte FIFO buffer for efficient data handling. It is housed in a 24-pin TQFN package (3.5x3.5 mm) with an exposed pad, suitable for surface-mount installation. The component supports IrDA, RS-232, and RS-485 protocols and includes an internal oscillator. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates a 128-word FIFO buffer to manage serial data transmission and reception efficiently.
• Supports multiple communication protocols including IrDA, RS-232, and RS-485 standards.
• Includes an internal oscillator to reduce external component requirements.
• Features automatic flow control capabilities for reliable data integrity.

Applications

• Industrial automation systems requiring robust serial communication
• Embedded devices utilizing IrDA or RS-485 interfaces
• Portable electronics operating on low-voltage power supplies

Procurement Notes

Verify the specific suffix 'V+' against official Analog Devices documentation to confirm temperature grade and RoHS compliance status. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the manufacturer's latest datasheet for any updates regarding pinout configurations or recommended operating conditions before finalizing procurement.

Selection Notes

Select this component when a single UART channel with high-speed support up to 24 Mb/s is required in a compact footprint. The internal oscillator simplifies design by eliminating external crystal dependencies. Consider the 128-byte FIFO depth for applications needing buffering against burst data traffic. Verify that the 24-TQFN package dimensions align with your assembly constraints and thermal management strategy.

Part Context

The MAX3107 belongs to the Maxim Integrated MAX3107 family of UART interface ICs. This series is designed to provide flexible serial communication solutions for embedded applications. The ETG/V+ designation indicates a specific tape-and-reel packaging option with extended temperature rating capabilities, distinguishing it from other variants in the same functional family.

Replacement Considerations

Consult Analog Devices official substitution guides for verified alternatives. Generic UART controllers may lack the specific 128-byte FIFO or protocol support found in this model. Ensure any replacement maintains compatibility with the 24-TQFN package and 1.65 V to 3.6 V supply range.
