MAX3223 3V to 5.5V Low Power RS-232 Transceiver with AutoShutdown

The MAX3223 is a specialized 3V to 5.5V RS-232 transceiver designed for battery-powered and portable applications. This device features a unique AutoShutdown mode that automatically powers down the drivers and internal power supply when no valid signal is detected on the receiver inputs, effectively saving energy and extending battery life. With its integrated charge pump, the MAX3223 requires only four small external capacitors to operate, simplifying circuit designs and reducing board space. It is fully compliant with EIA/TIA-232 standards and supports data rates up to 250kbps. This robust IC is ideal for use in laptops, handheld diagnostics equipment, and mobile peripherals where low power consumption and reliable serial data transmission are essential.

Key Features:

Revolutionary AutoShutdown feature reduces current to 1 microamp.

High data signaling rates up to 250kbps for fast communication.

Includes two drivers and two receivers for full duplex operation.

Enhanced ESD protection on bus pins for hardware reliability.

Integrated charge pump circuitry eliminates the need for external bipolar power.
