Overview

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 impedance state while the power supply stabilizes. The driver on the ISL3298EMRTEP is not limited, so it can achieve a 16Mbps data rate and is offered in the -55°C to +125°C temperature range. This devices also feature a logic supply pin (VL) that sets the switching points of the DE and DI inputs to be compatible with a lower supply voltage in mixed voltage systems. For a companion single RS-485 receiver in micro packages, see the ISL3282EMRTEP.
