MAX3221EEAE+ Description

Short technical summary and product information.

The MAX3221EEAE+ is a single-supply RS-232 transceiver designed for 3V operation. It offers high data rate capabilities and enhanced electrostatic discharge (ESD) protection, safeguarding against ±15kV IEC 1000-4-2 Air-Gap Discharge and ±8kV Contact Discharge, as well as ±15kV using the Human Body Model.

This transceiver utilizes Maxim's AutoShutdown feature, reducing supply current to 1µA when the RS-232 cable is disconnected or peripherals are off, thus saving power without requiring changes to existing BIOS or operating systems. It delivers true RS-232 performance from a +3.0V to +5.5V supply using a dual charge pump that requires only four small 0.1µF capacitors for operation from a +3.3V supply. The device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels.

The MAX3221E variant contains one driver and one receiver, making it suitable for space-constrained applications. It is available in space-saving TQFN, SSOP, and TSSOP packages, making it ideal for notebook, subnotebook, and handheld devices, as well as cellular phones and battery-powered equipment.
