SIT3485ISO Description

Short technical summary and product information.

The SIT3485ISO is a half-duplex RS-485 transceiver with integrated capacitive isolation, designed to meet TIA/EIA-485 standard requirements. It offers robust performance with a data transmission rate of up to 500kbps and supports up to 256 transceivers on a single communication bus due to its 1/8 unit load.

 

Key electrical features include a wide operating voltage range of 2.5V to 5.5V for VCC1 and 4.5V to 5.5V for VCC2. The device provides significant protection with over 15kV HBM ESD protection on the bus port, driver short-circuit protection, receiver open-circuit failure protection, fail-safe functionality, over-temperature protection, current-limiting protection, and over-voltage protection. It also features a low-power shutdown mode.

 

Operating across a wide temperature range of -40°C to 125°C, the SIT3485ISO boasts high Common-Mode Transient Immunity (CMTI) of ±100kV/µs and an isolation voltage resistance of up to 5000 VRMS. The transceiver is available in a wide-body SOIC16 package, suitable for surface mounting.

 

This component is ideal for applications requiring reliable and isolated serial communication in noisy electrical environments, such as industrial automation, energy storage systems, and automotive applications.
