3.
Features
* ▪ IEC61000 ESD protection on RS-485 I/O pins: ±15kV
* Class 3 ESD level on all other pins: >7kV HBM
▪ ±3kV EFT immunity of bus I/O pins ▪ Full fail-safe (open, short, terminated/floating)
receivers ▪ Hot plug - Tx and Rx outputs remain three-state
during power-up ▪ True 1/8 unit load allows
Applications
* Slew rate limited versions also include receiver input filtering to enhance noise immunity in the presence of slow input signals. The RAA788170, RAA788173, and RAA788176 are configured for full duplex (separate Rx input and Tx output pins) applications. The half duplex versions multiplex the Rx inp
