RS-485, RS-422 & RS-232

Intersil has a rich interface history dating back to the 1970’s. Our RS-485 and RS-422 transceivers are used by the biggest names in industrial process control, telecommunications, and hundreds of different applications.

Six ways Intersil enhances your RS-485 serial port

1. Ruggedized:
IEC61000 ESD, wide differential voltage, and full failsafe to protect your data port from faults
4. Low Power:
Operation down to 1.8v supply for remote or battery operated apps
2. Fault protected:  
Over Voltage Protected for DC faults that will damage the devices on the bus
5. Low cost:
Basic feature operating off of 5V and 3.3V supply
3. High Speed:  
Data rates from 40Mbps to 100Mbps for ultra-fast data transfer
6. Multi-protocol:  
Selectable RS-485 and RS-232 ports in one package
