Renesas Electronics ISL81487LIPZ Line Transceiver, 3-State

The Renesas Electronics ISL81487L devices are ESD protected, fractional unit load (UL), BiCMOS, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output/receiver input is protected against ±15kV ESD strikes without latch-up. Unlike competitive devices, this device family is specified for 10% tolerance supplies (4.5V to 5.5V).

RS-485 I/O pin ESD protection= ±15kV HBM
Class 3 ESD level on all other pins= >7kV HBM
Fractional unit load allows up to 256 devices on the bus
