Maxim Integrated MAX3313EEUB+T: High-Speed 3.0V to 5.5V, 460kbps, RS-232 Transceivers with AutoShutdown

The MAX3313EEUB+T from Maxim Integrated is a robust RS-232 transceiver designed to operate in a wide voltage range from 3.0V to 5.5V, making it suitable for a variety of applications that require reliable serial communication. This transceiver is capable of data rates up to 460kbps, offering high-speed performance for serial data exchange in industrial, commercial, and consumer products.

Encased in a compact 10-pin µMAX package, the MAX3313EEUB+T is engineered to conserve space on your PCB, making it an excellent choice for space-constrained applications. The device integrates an AutoShutdown™ feature, which automatically reduces the supply current to a mere 1µA when the device does not detect a valid signal transition on the receiver input for 30 seconds. This smart power-saving capability is ideal for battery-powered devices, extending operational life and reducing power consumption when the interface is inactive.

The MAX3313EEUB+T is designed with Maxim Integrated's proprietary technology, ensuring reliable operation even under the harshest conditions. It includes two drivers and two receivers, providing the necessary interfaces for full-duplex communication. The device also features a 1µA shutdown mode, a 2nA low-power shutdown mode, and a logic-level translation function that allows it to interface directly with 5V or 3.3V logic without requiring additional level shifters.

For enhanced protection, this transceiver includes a ±15kV ESD protection on transmitter outputs and receiver inputs, which safeguards the device against electrostatic discharges, making it more resilient in industrial environments. The MAX3313EEUB+T is also fully compliant with the EIA/TIA-232-F standards, ensuring compatibility with the vast majority of RS-232 systems.

Whether you are designing point-of-sale systems, data acquisition equipment, or any other application that requires a reliable and efficient serial interface, the MAX3313EEUB+T from Maxim Integrated is a versatile solution that combines performance, power efficiency, and compact design.
