The Union Semiconductor International Limited UM3483EESA is a low-power RS485 transceiver designed for reliable data transmission. It operates within a supply voltage range of 3V to 5.5V and supports half-duplex communication at data rates up to 500kbps.
This transceiver features enhanced electrostatic discharge (ESD) protection, rated to ±15kV using the Human Body Model and IEC61000-4-2 Air-Gap Discharge, and ±8kV using IEC61000-4-2 Contact Discharge. The slew-rate-limited driver minimizes EMI and reduces reflections, contributing to error-free data transmission.
Designed for industrial and telecommunications applications, the UM3483EESA includes features such as thermal shutdown and current-limiting for driver overload protection. It also offers a fail-safe receiver input that guarantees a logic-high output under open, shorted, or idle bus conditions. The device is available in a compact 8-SOP surface mount package.
With a typical quiescent current of 300μA during operation and 1μA in shutdown mode, this transceiver offers significant power savings. Its CMOS design ensures ruggedness against overload and ESD damage, making it suitable for demanding environments.
