Description and Introduction
Low Power, +3.3 V, RS-232 Line Drivers/Receivers The ADM3222ARU is a dual-channel RS-232 line driver/receiver manufactured by Analog Devices. It operates with a supply voltage range of 3.0V to 5.5V, making it suitable for both 3.3V and 5V systems. The device features two drivers and two receivers, supporting data rates up to 460 kbps. It includes an onboard charge pump, which eliminates the need for external capacitors, simplifying design and reducing board space. The ADM3222ARU is designed to meet the EIA/TIA-232 and V.28/V.24 specifications, ensuring compatibility with standard RS-232 interfaces. It is available in a 16-lead TSSOP package and operates over an industrial temperature range of -40°C to +85°C. The device also includes enhanced ESD protection, with ±15 kV on the RS-232 bus pins, ensuring robust performance in harsh environments.
