Description: The ISL3298EMRTEP is a ±16. 5kV HBM ESD Protected (7kV IEC61000 contact), 3. 0V to 5. 5V powered, single transmitter for balanced communication using the RS-485 and RS-422 standards. This driver has very low bus currents (±40mA); therefore, it presents less than a 1/8 unit load to the RS-485 bus. This allows more than 256 transmitters on the network without violating the RS-485 specification 32 unit load maximum, and without using repeaters. Hot Plug circuitry ensures that the Tx outputs remain in a high im
