INTERSIL ±15kV ESD Protectio，3.3V，Low Power, High Speed RS-485/RS-422 Transceiver

INTERSIL ±15kV ESD Protectio，3.3V，Low Power, High Speed RS-485/RS-422 Transceiver Description:

Intersil ISL8307XE are BiCMOS 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. These devices have very low bus currents (+125mA/-100mA), so they present a true “1/8 unit load” to the RS-485 bus. This allows up to 256 transceivers on the network without violating the RS-485 specification’s 32 unit load maximum, and without using repeaters. For example, in a remote utility meter reading system, individual meter readings are routed to a concentrator via an RS-485 network, so the high allowed node count minimizes the number of repeaters required.
