The Renesas Electronics are Bi CMOS 3.3V powered, full fail-safe, Low Power, High Speed or Slew Rate limited ,single transceiver that meet both the RS-485 and RS-422 standards for balanced communication. these devices have very low bus current and it is allows up to 256 transceiver on the network. For example, in a remote utility meter reading system, individual meter readings are routed to a concentrator on network, high allowed node count. in this hot plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state while the power supply stabilizes.
