The MAX3221CUE+ is a 1-driver, 1-receiver RS-232 transceiver designed for applications requiring low power consumption. It operates from a single +3.0V to +5.5V supply, eliminating the need for a ±12V supply thanks to its integrated charge pump circuitry.
Key features include a supply current of just 1µA in shutdown mode, activated by the AutoShutdown™ feature when no valid signal is detected on receiver inputs for 30µs. This makes it suitable for battery-powered and hand-held equipment.
The device supports a data rate of 235Kbps and requires minimal external components, needing only 0.1µF capacitors for 3.3V operation. It is housed in a 16-TSSOP package suitable for surface mounting.
Applications include battery-powered equipment, hand-held devices, peripherals, and portable diagnostic equipment where power efficiency and true RS-232 performance are critical.
