Maxim Integrated MAX207EEAG-T Interface - Drivers & Receivers

The MAX207EEAG-T from Maxim Integrated is a robust, high-performance interface IC designed for serial communication in industrial, networking, and telecommunication applications. This device is part of the MAX207E series and comes in a 24-SSOP (0.209", 5.30mm Width) package. It is specifically engineered to facilitate RS-232 and V.28 serial protocols, ensuring reliable data transmission even under challenging conditions.

The MAX207EEAG-T features a dual charge pump circuitry that allows the IC to deliver true RS-232 performance from a single 5V power supply. This innovative design eliminates the need for additional ±12V power supplies, simplifying the overall design and reducing power consumption. The charge pump requires only four small 0.1µF external capacitors, which contributes to a reduced PCB footprint and a more compact overall design.

With its ability to operate at a data rate of up to 120kbps, the MAX207EEAG-T is well-suited for applications that require efficient and speedy data transfer. The device also includes a shutdown mode that reduces power consumption to just 1µW, making it an excellent choice for power-sensitive applications.

The MAX207EEAG-T is equipped with a total of two drivers and two receivers. The drivers maintain a ±5V output swing and are capable of driving up to 10 receivers each. The receivers can handle up to ±30V input levels, providing a substantial margin above the standard RS-232 threshold levels for enhanced data integrity.

This interface IC also features a proprietary low-dropout transmitter output stage, delivering a ±5.0V output swing for data rates up to 120kbps. The MAX207EEAG-T is designed with receiver hysteresis to improve noise rejection, ensuring a more stable and reliable communication link.

Overall, the MAX207EEAG-T is a versatile and durable choice for designers looking to implement RS-232 communication with minimal power draw and space requirements. Its combination of high data rate, low-power shutdown, and robust electrostatic discharge (ESD) protection up to ±15kV makes it a practical component for a wide range of applications.
