ADM211EARS Description

Short technical summary and product information.

The ADM211EARS is a robust RS-232 transceiver from the ADM2xxE family, designed for operation in harsh electrical environments. It complies with the EIA-232-E and CCITT V.28 specifications and operates from a single 5V power supply (4.5V to 5.5V). The device integrates four drivers and five receivers in a full-duplex configuration, supporting a guaranteed data rate of 230 kbps.

 

ESD protection is provided on all I/O lines, with IEC 1000-4-2 contact discharge of ±8 kV, air-gap discharge of ±15 kV, and human body model protection of ±15 kV. The transceiver also features a low-power shutdown mode consuming only 1 µW, making it suitable for power-sensitive applications. Receiver hysteresis of 650 mV ensures noise immunity.

 

The ADM211EARS is offered in a 28-SSOP (0.209", 5.30mm Width) surface-mount package and operates over an industrial temperature range of -40°C to +85°C. It is ideal for use in laptops, notebooks, printers, peripherals, and modems where reliable serial communication and EMC compliance are required.
