The ADM239LJR is a low power RS-232 transceiver designed for EIA-232-E and V.28 communication interfaces. It integrates three drivers and five receivers, making it suitable for multi-channel serial communication. The device operates from a single +5V supply and uses an internal charge pump to generate the required ±9V output swing. It supports data rates up to 120 kbps.
The ADM239LJR features a low power shutdown mode that reduces supply current to less than 1 µA, ideal for battery-powered equipment. The receiver inputs can tolerate ±30V, providing robust protection. The device is part of the ADM2xxL family, offering enhanced performance with lower power consumption and faster slew rate compared to earlier generations.
The transceiver is available in a 24-pin SOIC wide body package (24-SOIC) for surface mount assembly. It is designed for use in computers, peripherals, modems, printers, and instruments where RS-232 communication is required. The part requires minimal external components, typically only 1 µF capacitors for the charge pumps.
